CRYSTAL STRUCTURE OF ISOCITRATE LYASE FROM MYCOBACTERIUM TUBERCULOSIS

Structural highlights

1f61 is a 2 chain structure. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Activity:	Isocitrate lyase, with EC number 4.1.3.1
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT, TOPSAN

Function

[ACEA_MYCTU] Catalyzes the formation of succinate and glyoxylate from isocitrate, a key step of the glyoxylate cycle. May be involved in the assimilation of one-carbon compounds via the isocitrate lyase-positive serine pathway (By similarity).

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

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.
