Characterization of the χψ subcomplex of Pseudomonas aeruginosa DNA polymerase III.

KT2440 chi–psi cloning/purification and low-salt ssDNA binding, plus homologous subunit attribution experiments.

PMID:16210315

Discovery and characterization of the cryptic psi subunit of the pseudomonad DNA replicase.

P. aeruginosa native-complex identification and reconstitution establish divergent psi as a functional loader accessory subunit; comparative mechanism for KT2440.

PMID:17210572

A function for the psi subunit in loading the Escherichia coli DNA polymerase sliding clamp.

E. coli psi stabilizes the loader ATP-dependent high-DNA-affinity state; comparative evidence, not a KT2440 measurement.

KT2440 chi–psi identity and construct mapping

Official supplement primer mapping identifies PP_0696/Q88Q02; current291-residue translation and corrected261-residue native protein are distinguished.

UniProt entry Q88Q02 for holD

The frozen sequence/accession identifies PP_0696. Its ProtNLM Energy transducer TonB label is a machine prediction contradicted by primary clone-to-sequence mapping and is not used as functional evidence.
