UniProtKB - B6V2N4 (PORTL_BPSP1)
Protein
Probable portal protein
Gene
3.1
Organism
Bacillus phage SP01 (Bacteriophage SP01)
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
