2',4' DINITROPHENYL-2-DEOXY-2-FLURO-B-D-CELLOBIOSIDE COMPLEX OF THE ENDOGLUCANASE CEL5A FROM BACILLUS AGARADHAERENS AT 1.6 A RESOLUTION
Overview
The enzymatic hydrolysis of O-glycosidic linkages is one of the most, diverse and widespread reactions in nature and involves a classic, "textbook" enzyme mechanism. A multidisciplinary analysis of a, beta-glycoside hydrolase, the Cel5A from Bacillus agaradhaerens, is, presented in which the structures of each of the native, substrate, covalent-intermediate, and product complexes have been determined and, their interconversions analyzed kinetically, providing unprecedented, insights into the mechanism of this enzyme class. Substrate is bound in a, distorted 1S3 skew-boat conformation, thereby presenting the anomeric, carbon appropriately for nucleophilic attack as well as satisfying the, stereoelectronic requirements for an incipient oxocarbenium ion. Leaving, group departure results in ... [(full description)]
