CRYSTAL STRUCTURE OF PSEUDOMONAS AERUGINOSA LECTIN 1 COMPLEXED WITH GALACTOSE AT 1.6 A RESOLUTION
Overview
The structure of the tetrameric Pseudomonas aeruginosa lectin I (PA-IL) in complex with galactose and calcium was determined at 1.6 A resolution, and the native protein was solved at 2.4 A resolution. Each monomer adopts a beta-sandwich fold with ligand binding site at the apex. All galactose hydroxyl groups, except O1, are involved in a hydrogen bond network with the protein and O3 and O4 also participate in the co-ordination of the calcium ion. The stereochemistry of calcium galactose binding is reminiscent of that observed in some animal C-type lectins. The structure of the complex provides a framework for future design of anti-bacterial compounds.
