CRYSTAL STRUCTURE OF ISOCITRATE LYASE FROM MYCOBACTERIUM TUBERCULOSIS
Overview
Isocitrate lyase (ICL) plays a pivotal role in the persistence of Mycobacterium tuberculosis in mice by sustaining intracellular infection in inflammatory macrophages. The enzyme allows net carbon gain by diverting acetyl-CoA from beta-oxidation of fatty acids into the glyoxylate shunt pathway. Given its potential as a drug target against persistent infections, we solved its structure without ligand and in complex with two inhibitors. Covalent modification of an active site residue, Cys 191, by the inhibitor 3-bromopyruvate traps the enzyme in a catalytic conformation with the active site completely inaccessible to solvent. The structure of a C191S mutant of the enzyme with the inhibitor 3-nitropropionate provides further insight into the reaction mechanism.
