ENDOGLUCANASE I COMPLEXED WITH NON-HYDROLYSABLE SUBSTRATE ANALOGUE
Overview
Endoglucanase I (EG I) is a cellulase, from glycosyl hydrolase family 7, which cleaves the beta-1,4 linkages of cellulose with overall retention of, configuration. The structure of the EG I from Fusarium oxysproum, complexed to a nonhydrolyzable thiooligosaccharide substrate analogue, has, been determined by X-ray crystallography at a resolution of 2.7 A, utilizing the 4-fold noncrystallographic symmetry present in the, asymmetric unit. The electron density map clearly reveals the presence of, three glucosyl units of the inhibitor, consistent with the known number of, sugar-binding subsites, located at the active site of the enzyme in the, -2, -1, and +1 subsites, i.e., actually spanning the point of enzymatic, cleavage. The pyranose ring at the point of potential enzymatic cleavage, is ... [(full description)]
