===STRUCTURE OF TAILSPIKE-PROTEIN===

~~==Overview==~~

<!--

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.

The line below this paragraph, {{ABSTRACT_PUBMED_8855221}}, adds the Publication Abstract to the page

(as it appears on PubMed at http://www.pubmed.gov), where 8855221 is the PubMed ID number.
