Probable portal protein

Gene

34

Organism
Streptomyces phage phiC31 (Bacteriophage phi-C31)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

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
