PSEUDOMONAS AERUGINOSA LECTIN II (PA-IIL) TOGETHER WITH FUCOSE
Overview
Pseudomonas aeruginosa galactose- and fucose-binding lectins (PA-IL and, PA-IIL) contribute to the virulence of this pathogenic bacterium, which is, a major cause of morbidity and mortality in cystic fibrosis patients. The, crystal structure of PA-IIL in complex with fucose reveals a tetrameric, structure. Each monomer displays a nine-stranded, antiparallel b-sandwich, arrangement and contains two close calcium cations that mediate the, binding of fucose in a recognition mode unique among carbohydrate-protein, interactions. Experimental binding studies, together with theoretical, docking of fucose-containing oligosaccharides, are consistent with the, assumption that antigens of the Lewis a (Le(a)) series may be the, preferred ligands of this lectin. Precise knowledge of the lectin-binding, site should allow a better design of new antibacterial-adhesion, prophylactics.
