1.W.2.1.1
Phage T5 portal protein of 403 aas (Huet et al. 2016). It forms the portal vertex of the capsid and plays a role in governing correct capsid geometry.
This portal plays critical roles in capsid assembly, genome packaging,
head completion protein attachment, and genome ejection.
The portal protein multimerizes as a single ring-shaped homododecamer
arranged around a central channel (By similarity). It binds to the
terminase subunits to form the packaging machine (Huet et al. 2016).
