LONG FATTY ACID CHAIN ENOYL-ACP REDUCTASE (INHA) IN COMPLEX WITH AN ISONICOTINIC-ACYL-NADH INHIBITOR

Overview

The preferred antitubercular drug isoniazid specifically targets a, long-chain enoyl-acyl carrier protein reductase (InhA), an enzyme, essential for mycolic acid biosynthesis in Mycobacterium tuberculosis., Despite the widespread use of this drug for more than 40 years, its, precise mode of action has remained obscure. Data from x-ray, crystallography and mass spectrometry reveal that the mechanism of, isoniazid action against InhA is covalent attachment of the activated form, of the drug to the nicotinamide ring of nicotinamide adenine dinucleotide, bound within the active site of InhA.

About this Structure
