DNA-binding protein J

Gene

J

Organism
Enterobacteria phage phiK (Bacteriophage phi-K)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Mediates ssDNA packaging into virion, it locates to the internal surface of the capsid, thereby displacing the internal scaffolding protein B during virion formation. Protein J binds to and is packaged with the viral ssDNA. Additionally, protein J plays a role in viral attachment efficiency to the host cell.By similarity

Miscellaneous

Phi KhT, a host-range mutant of phi K, can grow on E.coli C and B, besides K12, and is more thermosensitive than the parental phage phi K.
