UniProtKB entry P15076 (VG02_BPT4)
-
gp2 binds to the viral DNA ends and protects the viral genomic DNA against degradation by the host RecBCD exonuclease.
"Binds to the viral DNA ends and protects the viral DNA against recBCD mediated degradation."
Deep research literature synthesis for bacteriophage T4 gene 2 (gp2)
-
gp2 (historically also called gp64) caps injected linear T4 dsDNA ends in Escherichia coli to prevent degradation by host RecBCD (exonuclease V).
"Enterobacteria phage T4 **gene 2** encodes **gp2** (historically also called **gp64**), a small, highly basic virion-associated protein that **protects the linear T4 dsDNA termini from degradation by host exonuclease V (ExoV; RecBCD complex)** immediately upon injection into the host cytoplasm."
