The research report should be a detailed narrative explaining the function, biological processes, and localization of the gene product. Citations should be given for all claims.
You should prioritize authoritative reviews and primary scientific literature when conducting research. You can supplement
this with annotations you find in gene/protein databases, but these can be outdated or inaccurate.
We are specifically interested in the primary function of the gene - for enzymes, what reaction is catalyzed, and what is the substrate specificity? For transporters, what is the substrate? For structural proteins or adapters, what is the broader structural role? For signaling molecules, what is the role in the pathway.
We are interested in where in or outside the cell the gene product carries out its function.
We are also interested in the signaling or biochemical pathways in which the gene functions. We are less interested in broad pleiotropic effects, except where these elucidate the precise role.
Include evidence where possible. We are interested in both experimental evidence as well as inference from structure, evolution, or bioinformatic analysis. Precise studies should be prioritized over high-throughput, where available.
The target protein is gene product 46 (gp46) from Enterobacteria phage T4, UniProt P04522, historically annotated as part of a T4 exonuclease complex. The modern consensus from genetics and biochemistry is that gp46 is the Rad50-family ATPase subunit of a phage Mre11–Rad50 (MR)–like DNA end-processing complex formed with gp47 (Mre11 homolog); this complex is required in vivo for homologous recombination, recombination-dependent DNA replication (RDR), and double-strand break (DSB) repair. (kreuzer1995recombinationdependentdnareplication pages 1-2, albrecht2012disruptionofthe pages 1-2, herdendorf2014catalyticmechanismof pages 1-2)
| Aspect | Evidence-backed summary | Key source(s) |
|---|---|---|
| identity/domains | Verified target: Enterobacteria phage T4 gene 46 / gp46 corresponds to the Rad50 homolog of the T4 gp46/gp47 DNA end-processing complex, matching the UniProt P04522 context. Biochemical and genetic literature consistently treats gp46 as an ABC/SMC-like ATPase with a conserved nucleotide-binding domain; this aligns with UniProt/InterPro assignment to P-loop NTPase / Rad50-SbcC AAA+ family. | Herdendorf & Nelson 2014, Biochemistry, doi:10.1021/bi500558d, https://doi.org/10.1021/bi500558d; Albrecht et al. 2012, J Biol Chem, doi:10.1074/jbc.M112.392316, https://doi.org/10.1074/jbc.M112.392316 (herdendorf2014catalyticmechanismof pages 1-2, albrecht2012disruptionofthe pages 1-2) |
| complex partners | gp46 functions with gp47 (the T4 Mre11 homolog) as the T4 MR complex; biochemical interaction data also support association of gp46/gp47 with UvsY, linking DNA end resection to presynaptic filament assembly during recombination. | Bleuit et al. 2001, PNAS, doi:10.1073/pnas.131007498, https://doi.org/10.1073/pnas.131007498; Albrecht et al. 2012, J Biol Chem, https://doi.org/10.1074/jbc.M112.392316 (bleuit2001mediatorproteinsorchestrate pages 2-3, albrecht2012disruptionofthe pages 1-2, bleuit2001mediatorproteinsorchestrate media 03c6cc3c) |
| enzymatic activities | The primary catalytic activity of the complex is 5′→3′ dsDNA exonuclease activity, genetically assigned to gp46/gp47 and biochemically observed in reconstituted assays; gp46 itself is also an ATP-binding/hydrolyzing enzyme whose ATPase is strongly stimulated by gp47 and DNA. Thus, gp46 is best annotated as the ATPase/structural motor subunit of an exonuclease complex rather than the nuclease active site itself. | Bleuit et al. 2001, PNAS, https://doi.org/10.1073/pnas.131007498; Herdendorf & Nelson 2014, Biochemistry, https://doi.org/10.1021/bi500558d (bleuit2001mediatorproteinsorchestrate pages 2-3, herdendorf2014catalyticmechanismof pages 1-2) |
| substrate specificity | Available data support activity on DNA ends, especially double-stranded DNA substrates requiring 5′-strand resection to generate recombinogenic 3′ ssDNA tails. Structural/mechanistic work indicates Rad50 can partially occlude nuclease sites such that ssDNA more readily accesses Mre11/gp47 nuclease sites, consistent with staged processing of DNA ends rather than indiscriminate nucleolysis. | Mosig 1998, Annu Rev Genet, doi:10.1146/annurev.genet.32.1.379, https://doi.org/10.1146/annurev.genet.32.1.379; Albrecht et al. 2012, J Biol Chem, https://doi.org/10.1074/jbc.M112.392316 (mosig1998recombinationandrecombinationdependent pages 8-10, albrecht2012disruptionofthe pages 2-3) |
| mechanistic model | Current model: gp46 binds/hydrolyzes ATP at the Rad50 head dimer interface; ATP-driven conformational cycling promotes assembly at DNA ends and transitions to a translocation state that supports processive nuclease action by gp47. Work on the T4 MR system supports a two-state mechanism (initiation/assembly vs translocation), with allosteric communication from gp47 to gp46 required for full ATPase activation. | Albrecht et al. 2012, J Biol Chem, https://doi.org/10.1074/jbc.M112.392316; Herdendorf & Nelson 2014, Biochemistry, https://doi.org/10.1021/bi500558d (albrecht2012disruptionofthe pages 2-3, herdendorf2014catalyticmechanismof pages 1-2, albrecht2012disruptionofthe pages 10-11) |
| pathway/biological role | gp46 is essential in vivo for homologous recombination, double-strand break repair, and recombination-dependent DNA replication (RDR) in bacteriophage T4. Genetic studies show gene 46 mutants are strongly recombination-defective, and plasmid/phage assays place gp46 among the core factors needed to repair DSBs through replication-coupled pathways. | Kreuzer et al. 1995, J Bacteriol, doi:10.1128/jb.177.23.6844-6853.1995, https://doi.org/10.1128/jb.177.23.6844-6853.1995; George & Kreuzer 1996, Genetics, doi:10.1093/genetics/143.4.1507, https://doi.org/10.1093/genetics/143.4.1507; Mosig 1998, https://doi.org/10.1146/annurev.genet.32.1.379 (kreuzer1995recombinationdependentdnareplication pages 1-2, mosig1998recombinationandrecombinationdependent pages 8-10) |
| localization/cellular context | No evidence supports a virion structural role or extracellular localization. Function is best placed in the infected E. coli cytoplasm, where gp46 acts on phage DNA replication/recombination intermediates and damaged DNA ends; older work also reported a membrane-associated DNase activity controlled by genes 46/47, but the strongest modern interpretation is a DNA-metabolic role in intracellular nucleoprotein complexes rather than stable membrane localization. | Claudia & Wiberg 1981, J Virol, doi:10.1128/JVI.40.1.65-77.1981, https://doi.org/10.1128/JVI.40.1.65-77.1981; Liu & Morrical 2010, Virology Journal, doi:10.1186/1743-422X-7-357, https://doi.org/10.1186/1743-422X-7-357 (mosig1998recombinationandrecombinationdependent pages 8-10, bleuit2001mediatorproteinsorchestrate pages 2-3) |
| key quantitative data | Reported quantitative findings include: gp46 ATPase kcat ≈ 0.15 s⁻¹ alone and ≈ 3.2 s⁻¹ with gp47 + dsDNA (~20-fold activation); ATPase cooperativity increases from Hill ~1.4 (gp46 alone) to ~2.4 (MR-D complex). In a dsDNA exonuclease assay, retained label fell from 100% control to 44% with gp46 alone and to 14% with gp46+gp47, supporting gp47 stimulation of nuclease function. An Mre11-interface mutant reduced dsDNA exonuclease activity by ~10-fold under processive conditions. | Herdendorf & Nelson 2014, Biochemistry, https://doi.org/10.1021/bi500558d; Bleuit et al. 2001, PNAS, https://doi.org/10.1073/pnas.131007498; Albrecht et al. 2012, J Biol Chem, https://doi.org/10.1074/jbc.M112.392316 (albrecht2012disruptionofthe pages 2-3, herdendorf2014catalyticmechanismof pages 1-2, herdendorf2014catalyticmechanismof pages 2-3, bleuit2001mediatorproteinsorchestrate pages 2-3, bleuit2001mediatorproteinsorchestrate media 03c6cc3c) |
| recent 2023-2024 developments | Direct 2023-2024 gp46-specific primary literature appears limited, but recent cross-system structural work strengthened inference: a 2024 yeast MR cryo-EM study mapped conserved Rad50 ATP- and DNA-contacting residues and explicitly linked corresponding T4 gp46 residues to reduced ATP binding/hydrolysis and defective gp47-dependent nuclease activity, reinforcing mechanistic conservation between phage and eukaryotic MR complexes. | Petrini et al. 2024, Research Square preprint, doi:10.21203/rs.3.rs-5390974/v1, https://doi.org/10.21203/rs.3.rs-5390974/v1 (petrini2024structureguidedfunctional pages 4-7, petrini2024structureguidedfunctional pages 7-9) |
| applications | No established 2023-2024 biotechnology application specifically uses gp46 itself. Modern T4-derived applications in diagnostics primarily exploit other recombination proteins (UvsX, UvsY, gp32) in RPA/SIBA isothermal amplification platforms. Therefore, gp46 is currently more important as a mechanistic model for MR/Rad50 biology than as a routine applied reagent. | Morrical 2025, EcoSal Plus, doi:10.1128/ecosalplus.esp-0003-2025, https://doi.org/10.1128/ecosalplus.esp-0003-2025; Liu et al. 2024, Front Cell Infect Microbiol, doi:10.3389/fcimb.2024.1281827, https://doi.org/10.3389/fcimb.2024.1281827; Anbazhagan et al. 2024, 3 Biotech, doi:10.1007/s13205-024-04055-x, https://doi.org/10.1007/s13205-024-04055-x (morrical2025thebacteriophaget4 pages 9-12) |
Table: This table condenses the strongest evidence on the identity, biochemical role, pathway function, mechanistic model, and recent context for Enterobacteria phage T4 gene 46 (gp46; UniProt P04522). It is useful as a compact functional annotation that distinguishes direct evidence from broader pathway and comparative inferences.
RDR in phage T4 is a replication initiation/restart mode that uses recombination intermediates (e.g., D-loops, broken DNA ends) to reconstitute active replication forks. A classic synthesis is Mosig’s review, which emphasizes that recombination and DNA replication are tightly coupled in T4 and that genes 46 and 47 are essential for recombination and are implicated in processing DNA to create recombinogenic substrates for strand invasion and restart. (Mosig 1998, published Dec 1998; https://doi.org/10.1146/annurev.genet.32.1.379) (mosig1998recombinationandrecombinationdependent pages 8-10)
The T4 gp46/gp47 complex is functionally analogous to cellular Mre11–Rad50 systems that recognize and process DSB ends. In T4, gp46 is the Rad50 homolog (ATPase/motor-like subunit), while gp47 is the Mre11 homolog (nuclease subunit). Disrupting the Mre11-like subunit’s interface can impair allosteric activation of gp46 ATP hydrolysis and reduce processive exonuclease activity, supporting a coupled motor–nuclease mechanism. (Albrecht et al. 2012, published Sep 2012; https://doi.org/10.1074/jbc.M112.392316) (albrecht2012disruptionofthe pages 1-2, albrecht2012disruptionofthe pages 10-11)
Although UniProt labels P04522 as “Exonuclease subunit 2,” the best-supported mechanistic interpretation from biochemical studies is:
- The MR complex displays 5′→3′ dsDNA exonuclease activity, genetically assigned to gp46/47 and measurable in reconstituted systems. (bleuit2001mediatorproteinsorchestrate pages 2-3)
- gp46’s primary biochemical role is ATP binding/hydrolysis (Rad50-like ABC/SMC ATPase), which is strongly stimulated by gp47 and DNA and helps drive conformational changes and translocation states that enable processive nuclease function. (herdendorf2014catalyticmechanismof pages 1-2, albrecht2012disruptionofthe pages 2-3)
(A) ATPase activity (gp46 as Rad50 ATPase)
Gp46 is an ABC/SMC-like ATPase whose ATP turnover is weak alone but strongly activated in the presence of gp47 and dsDNA. Quantitatively, gp46 ATPase has kcat ≈ 0.15 s⁻¹ alone and increases to kcat ≈ 3.2 s⁻¹ with gp47 and dsDNA (≈20-fold activation), consistent with an ATP-driven conformational cycle in the assembled MR–DNA complex. (Albrecht et al. 2012; https://doi.org/10.1074/jbc.M112.392316) (albrecht2012disruptionofthe pages 2-3)
Kinetic dissection of ATP hydrolysis indicates increased positive cooperativity in the activated state (Hill coefficient ~2.4 for MR–DNA vs ~1.4 for gp46 alone) and supports a model in which ATP hydrolysis proceeds through an asymmetric, dissociative-like transition state, with chemistry likely rate-limiting under the examined conditions. (Herdendorf & Nelson 2014, published Aug 2014; https://doi.org/10.1021/bi500558d) (herdendorf2014catalyticmechanismof pages 1-2, herdendorf2014catalyticmechanismof pages 2-3)
(B) Exonuclease activity (MR complex)
In vitro assays consistent with exonuclease action show that gp46 alone causes partial degradation of a blunt dsDNA substrate, and addition of gp47 strongly increases degradation. In a representative experiment, the retained label on uniformly labeled dsDNA fell from 100% (control) to 44% with gp46, and to 14% with gp46+gp47. (Bleuit et al. 2001, published Jul 2001; https://doi.org/10.1073/pnas.131007498) (bleuit2001mediatorproteinsorchestrate pages 2-3)
The corresponding assay summary table and model figure were extracted from the source (Table 2 and Figure 2). (bleuit2001mediatorproteinsorchestrate media e27cae80, bleuit2001mediatorproteinsorchestrate media 665e248d)
Genetic and mechanistic syntheses support that gene 46/47 functions generate or process DNA structures needed for recombination—e.g., converting nicks to gaps or processing ends to generate ssDNA for recombinase loading. (mosig1998recombinationandrecombinationdependent pages 8-10)
Mechanistically, the MR complex is interpreted as acting at DNA ends produced by DSBs or replication fork collapse, coordinating ATP-driven transitions with nuclease processing. A two-state scheme (initiation/assembly vs translocation) has been proposed for nuclease progression, where ATP hydrolysis promotes a translocation state enabling processive nucleotide removal; a mutation disrupting the Mre11 dimer interface reduces dsDNA exonuclease activity ~10-fold under processive conditions. (albrecht2012disruptionofthe pages 1-2)
Severe recombination deficiency: Mutations in genes 46 and 47 cause a “most severe recombination deficiency,” consistent with central roles in T4 homologous recombination pathways. (Mosig 1998; https://doi.org/10.1146/annurev.genet.32.1.379) (mosig1998recombinationandrecombinationdependent pages 8-10)
RDR stimulated by DSBs: In vivo systems that model DSB-stimulated RDR identify gp46 and gp47 among key factors required for recombination-dependent replication, even though some earlier in vitro reconstitutions did not require them—highlighting that gp46/47 likely act on DNA–protein architectures or intermediates present in vivo. (Kreuzer et al. 1995, published Dec 1995; https://doi.org/10.1128/jb.177.23.6844-6853.1995) (kreuzer1995recombinationdependentdnareplication pages 1-2)
Biochemical interaction data indicate physical association of gp46 and gp47 with each other and with the recombination mediator UvsY, suggesting coordination between end processing (resection) and assembly of recombinase filaments on ssDNA. (Bleuit et al. 2001; https://doi.org/10.1073/pnas.131007498) (bleuit2001mediatorproteinsorchestrate pages 2-3)
A schematic model explicitly links gp46/47-catalyzed resection to UvsY-mediated presynaptic filament assembly (Figure 2). (bleuit2001mediatorproteinsorchestrate media 665e248d)
Direct subcellular localization evidence is limited in the retrieved corpus. However, all functional evidence places gp46’s role within intracellular DNA metabolism during infection (processing phage DNA ends and recombination intermediates), i.e., in the E. coli cytoplasm where phage DNA replication and recombination occur. This is supported by pathway placement in genetic/biochemical studies of RDR and DSB repair in infected cells. (kreuzer1995recombinationdependentdnareplication pages 1-2, mosig1998recombinationandrecombinationdependent pages 8-10)
Older studies reported a membrane-associated DNase activity controlled by genes 46/47, which may reflect association of nuclease activity with cellular fractions under certain experimental conditions rather than an obligate membrane-localized function. (Claudia & Wiberg 1981, published Oct 1981; https://doi.org/10.1128/JVI.40.1.65-77.1981) (mosig1998recombinationandrecombinationdependent pages 8-10)
A notable theme in the T4 literature is deep conservation of recombination/repair systems. For example, yeast RAD52 can complement T4 gene 46 or 47 defects in E. coli-based assays, suggesting mechanistic overlap in recombination functions (though not specifying enzymology). (Bernstein & Bernstein 1989, published May 1989; https://doi.org/10.1128/jb.171.5.2265-2270.1989) (bernstein1989bacteriophaget4genetic pages 3-4)
The best evidence-supported functional annotation is:
gp46 is a Rad50-family ATPase that, in complex with gp47 (Mre11 nuclease), uses ATP-driven conformational cycling to support processive DNA end processing (exonucleolytic resection) required for T4 homologous recombination, DSB repair, and recombination-dependent DNA replication. (herdendorf2014catalyticmechanismof pages 1-2, albrecht2012disruptionofthe pages 1-2, bleuit2001mediatorproteinsorchestrate pages 2-3, kreuzer1995recombinationdependentdnareplication pages 1-2)
Direct 2023–2024 primary literature on T4 gp46 itself was sparse in retrieval. However, 2024 high-resolution cryo-EM and structure-guided functional analysis of the yeast MR complex mapped conserved Rad50 ATP-coordinating residues and explicitly connected them to prior mutational/biochemical results in bacteriophage T4 Rad50 (gp46). The manuscript notes that mutating the corresponding residues in T4 gp46 severely reduces ATP binding affinity and hydrolysis and also impairs gp47-dependent nuclease activity, strengthening the mechanistic linkage between conserved ATP coordination and nuclease function across evolution. (Petrini et al. 2024, published Dec 2024; https://doi.org/10.21203/rs.3.rs-5390974/v1) (petrini2024structureguidedfunctional pages 4-7, petrini2024structureguidedfunctional pages 7-9)
Modern, real-world implementations of T4 recombination proteins are strongest in isothermal nucleic acid amplification (e.g., recombinase polymerase amplification, RPA), which uses T4 proteins such as UvsX, UvsY, and gp32. A 2024 RPA-based diagnostic study reports reaction times on the order of minutes and clinically evaluated performance (e.g., agreement vs qPCR), explicitly listing these T4 recombination proteins among core components. (Liu et al. 2024, published Feb 2024; https://doi.org/10.3389/fcimb.2024.1281827) (mosig1998recombinationandrecombinationdependent pages 8-10)
A 2024 review of RPA–CRISPR integrations similarly describes the roles of UvsX (recombinase), UvsY (loading factor), and gp32 (SSB) in amplification workflows. (Anbazhagan et al. 2024, published Aug 2024; https://doi.org/10.1007/s13205-024-04055-x) (mosig1998recombinationandrecombinationdependent pages 8-10)
In the retrieved applied literature and a recent systems-level review of T4 homologous recombination applications, gp46/gp47 are not described as core reagents for the widely used RPA/SIBA amplification technologies, which primarily use UvsX/UvsY/gp32 plus a strand-displacing polymerase. Thus, gp46’s current “real-world” impact is mainly as a mechanistic model for Mre11–Rad50 biology rather than as a routine biotechnology enzyme component. (Morrical 2025, published Dec 2025; https://doi.org/10.1128/ecosalplus.esp-0003-2025) (morrical2025thebacteriophaget4 pages 9-12)
The key tables/figure supporting interaction and nuclease assay claims are shown in extracted images (Table 1, Table 2, Figure 2). (bleuit2001mediatorproteinsorchestrate media 03c6cc3c, bleuit2001mediatorproteinsorchestrate media e27cae80, bleuit2001mediatorproteinsorchestrate media 665e248d)
