STRUCTURE OF BETA-GLYCOSIDASE FROM SULFOLOBUS SOLFATARICUS IN COMPLEX WITH D-GALACTOHYDROXIMO-1,5-LACTAM

Overview

Transition-state mimicry is increasingly important both to understand, enzyme mechanism and to direct the synthesis of putative therapeutic, agents. X-ray crystallography is able to provide vital information on the, interactions between an enzyme and the potential inhibitor. Here we report, the structures, at approximately 2 A resolution, of a family GH1, beta-glycosidase from the hyperthermophilic archaeon Sulfolobus, solfataricus, in complex with both covalently (derived from, 2-fluoro-glycosides) and noncovalently (hydroximolactam) bound inhibitors., The enzyme has broad specificity, accommodating both gluco- and, galacto-configured substrates, and the crystallographic data demonstrate, that the only difference in the way these ligands bind lies in the, interactions between Gln18, ...
