STRUCTURE OF TC14; A C-TYPE LECTIN FROM THE TUNICATE POLYANDROCARPA MISAKIENSIS
Overview
C-type lectins are calcium-dependent carbohydrate-recognising proteins., Isothermal titration calorimetry of the C-type Polyandrocarpa lectin, (TC14) from the tunicate Polyandrocarpa misakiensis revealed the presence, of a single calcium atom per monomer with a dissociation constant of 2.6, microM, and confirmed the specificity of TC14 for D -galactose and related, monosaccharides. We have determined the 2.2 A X-ray crystal structure of, Polyandrocarpa lectin complexed with D -galactose. Analytical, ultracentrifugation revealed that TC14 behaves as a dimer in solution., This is reflected by the presence of two molecules in the asymmetric unit, with the dimeric interface formed by antiparallel pairing of the two, N-terminal beta-strands and hydrophobic interactions. TC14 adopts a, typical ... [(full description)]
