Function

[TSPE_BPP22] Non-covalently bound to the neck of the phage capsid and mediating attachment of the viral particle to host cell-surface polysaccharide. It displays endorhamnosidase enzymatic activity, hydrolyzing the alpha-1,3-O-glycosidic linkage between rhamnose and galactose of the O-antigen polysaccharide.^[1] ^[2]

Publication Abstract from PubMed

The O-antigenic repeating units of lipopolysaccharides from Salmonella serogroups A, B, and D1 serve as receptors for the phage P22 tailspike protein, which also has receptor destroying endoglycosidase (endorhamnosidase) activity, integrating the functions of both hemagglutinin and neuraminidase in influenza virus. Crystal structures of the tailspike protein in complex with oligosaccharides, comprising two O-antigenic repeating units from Salmonella typhimurium, Salmonella enteritidis, and Salmonella typhi 253Ty were determined at 1.8 A resolution. The active-site topology with Asp-392, Asp-395, and Glu-359 as catalytic residues was identified. Kinetics of binding and cleavage suggest a role of the receptor destroying endorhamnosidase activity primarily for detachment of newly assembled phages.
