Structural highlights
Function
BP44_BPMU Forms the central cylindrical hub of the baseplate and plays an important role in baseplate and tail assembly (Probable). Core component of the initiator complex that triggers the tail tube polymerization during tail assembly (Probable). Forms a conduit that probably functions as an extension of the tail tube allowing viral DNA release during ejection. Might facilitate the interaction of the virus with the host cell surface through electrostatic interactions during virus entry into host cell.
