M. SMEGMATIS ARYLAMINE N-ACETYL TRANSFERASE
Overview
Arylamine N-acetyltransferases which acetylate and inactivate isoniazid, an anti-tubercular drug, are found in mycobacteria including Mycobacterium, smegmatis and Mycobacterium tuberculosis. We have solved the structure of, arylamine N-acetyltransferase from M. smegmatis at a resolution of 1.7 A, as a model for the highly homologous NAT from M. tuberculosis. The fold, closely resembles that of NAT from Salmonella typhimurium, with a common, catalytic triad and domain structure that is similar to certain cysteine, proteases. The detailed geometry of the catalytic triad is typical of, enzymes which use primary alcohols or thiols as activated nucleophiles., Thermal mobility and structural variations identify parts of NAT which, might undergo conformational changes during catalysis.
