 25-111 6.70e-20

Baseplate wedge protein gp25; This family represents T4 phage gp25 protein and gp25-like proteins, found in several systems, including contractile tail bacteriophages, the type VI secretion system (T6SS) and R-type pyocins, which constitute a multiprotein tubular apparatus to attach to and penetrate host cell membranes. Gp25 is a component of the conserved wedge in the inner part of the baseplate and serves as a nucleus for sheath polymerization, playing a critical role in sheath assembly and contraction. The EPR motif (Glu-Pro-Arg, residues 85-87 of gp25) is conserved across all members of the family including orthologs from the RpoS-mediated general stress response system (called IraD). This motif interacts with the 'core bundle' composed of orthologs of T4 gp6 and gp7 proteins in contractile injection systems.
