Aleuria aurantia lectin displays novel binding mode for fucose. Crystal structure and ligand interaction of a new family of fucolectins.
Original language description
Aleuria aurantia lectin (AAL) is a fungal protein that specifically recognised fucose moiety in glycans. The crystal structure of AAL complexed with fucose has been solved at 1.5 A resolution. AAL displays a dimer composition, each subunit consists of asix-bladed beta-propeller fold and of a small antiparallel two-strands beta-sheet that play a role in dimerization. Primary sequence of AAL contains six internal repeats [1] corresponded to particular blades, crystal structure reveals five fucose molecules per AAL monomer in binding sites formed by two adjacent blades. Surface plasmon resonance experiments have been performed on a series of fucose containing oligosaccharides to determine equilibrium dissociation constants for lectine-oligosaccharide interaction. Measurements confirm the broad specificity of the lectin, with a slight preference for alpha-Fuc1-2Gal disaccharide. AAL shows high sequence similarity with a lectin from plant pathogenic bacterium Ralstonia solanacearum (RSL) [
