Abstract
|
|
|
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.
