Superfamily: Phage tail base-plate Siphoviridae RBP, head domain

This superfamily represents the domain found in a family of proteins expressed from ORF18 of the Lactococcus P2-like phage. This is one of three protein species, shoulders, neck, and head, that form the phage tail base-plate. In the overall structure this head domain exists as six trimers, and is necessary for specific recognition of the receptors at the host cell surface. Siphoviridae are the P2-like Caudovirales of Lactococcus PMID:20351260. This superfamily also includes DUF1914, according to Pfam.
