Family relationships



This entry represents absorption protein P2 (synonym: receptor-binding protein P2) from the bacteriophage PRD1. Absorption protein P2 is a multi-beta-sheet protein whose complicated topology forms an elongated seahorse-shaped molecule with a distinct head, containing a pseudo-beta propeller structure with approximate six-fold symmetry, and tail (beta-sandwich). It is required for the attachment of the phage to the host conjugative DNA transfer complex. This is a poorly understood large transmembrane complex of unknown architecture, with at least 11 different proteins [PMID: 12623018].
