UniProtKB - E1XTG6 (PORTL_BPSAV)
Protein
Portal protein
Gene
Vi01_157c
Organism
Salmonella phage ViI
Status
Functioni
Forms the portal vertex of the capsid. This portal plays critical roles in head assembly, genome packaging, neck/tail attachment, and genome ejection. The portal protein multimerizes as a single ring-shaped homododecamer arranged around a central channel. Binds to the terminase subunits to form the packaging machine.UniRule annotation
