ENDOGLUCANASE CEL5A FROM BACILLUS AGARADHAERENS IN THE ORTHORHOMBIC CRYSTAL FORM IN COMPLEX WITH CELLOTRIOSE

Overview

Non-covalent interactions between protein and ligand at the active centre, of glycosidases play an enormous role in catalysis. Dissection of these, hydrogen-bonding networks is not merely important for an understanding of, enzymatic catalysis, but is also increasingly relevant for the design of, transition-state mimics, whose tautomeric state, hydrogen-bonding, interactions and protonation contribute to tight binding. Here, atomic, resolution ( approximately 1 A) analysis of a series of complexes of the, 34 kDa catalytic core domain of the Bacillus agaradhaerens endoglucanase, Cel5A is presented. Cel5A is a 'retaining' endoglucanase which performs, catalysis via the formation and subsequent breakdown of a covalent, glycosyl-enzyme intermediate via oxocarbenium-ion-like transition states., ...
