Protein attributes

Sequence length	263 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Probably triggers with protein G the injection of the phage DNA into the host upon conformational changes induced by virus-host receptor interaction By similarity.
Subcellular location	Virion Potential.
Sequence similarities	Belongs to the microviridae H protein family.
Sequence caution	The sequence BAA00506.1 differs from that shown. Reason: Erroneous initiation. The sequence BAA00507.1 differs from that shown. Reason: Erroneous initiation.
