| Enzyme Function | FUNCTION: 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. {ECO:0000255|HAMAP-Rule:MF_04114}. |
