Function
PORTL_BPSPP Forms the portal vertex of the capsid (PubMed:17363899). 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.[1]
