DNA-binding protein J

Gene

J

Organism
Enterobacteria phage alpha3 (Bacteriophage alpha-3)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

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
