This domain is found at the C-terminal of bacteriophage PRD1 spike protein P5. [1]. The spike structure of bacteriophage PRD1 is comprised of proteins P2, P5, and P31. P5 is an elongated multidomain trimer. This C-terminal domain appears to contain the residues responsible for the trimerization of the protein [1,2].	Domain
