VIBRIO CHOLERAE NEURAMINIDASE
Overview
BACKGROUND: Vibrio cholerae neuraminidase is part of a mucinase complex, which may function in pathogenesis by degrading the mucin layer of the, gastrointestinal tract. The neuraminidase, which has been the target of, extensive inhibitor studies, plays a subtle role in the pathology of the, bacterium, by processing higher order gangliosides to GM1, the receptor, for cholera toxin. RESULTS: We report here the X-ray crystal structure of, V. cholerae neuraminidase at 2.3 A resolution. The 83 kDa enzyme folds, into three distinct domains. The central catalytic domain has the, canonical neuraminidase beta-propeller fold, and is flanked by two domains, which possess identical legume lectin-like topologies but without the, usual metal-binding loops. The active site has many features in common, ... [(full description)]
