E78R MUTANT OF A CARBOHYDRATE BINDING MODULE FAMILY 29

Overview

The structural and thermodynamic basis for carbohydrate-protein, recognition is of considerable importance. NCP-1, which is a component of, the Piromyces equi cellulase/hemicellulase complex, presents a provocative, model for analyzing how structural and mutational changes can influence, the ligand specificity of carbohydrate-binding proteins. NCP-1 contains, two "family 29" carbohydrate-binding modules designated CBM29-1 and, CBM29-2, respectively, that display unusually broad specificity; the, proteins interact weakly with xylan, exhibit moderate affinity for, cellulose and mannan, and bind tightly to the beta-1,4-linked, glucose-mannose heteropolymer glucomannan. The crystal structure of, CBM29-2 in complex with cellohexaose and mannohexaose identified key, residues involved in ligand ... [(full description)]
