UniProtKB - B0ZSF2 (PORTL_BPHA1)
Protein
Probable portal protein
Gene
HAPgp04
Organism
Halomonas phage phiHAP-1 (isolate -/Gulf of Mexico/-/2001) (Bacteriophage phiHAP-1)
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.By similarity
