isocitrate lyase  M-CSA #272

Isocitrate lyase catalyses the reversible lysis of a C-C bond of isocitrate to form glycoxylate and succinate. The enzyme directs acetyl-CoA away from beta-oxidation of fatty acids into the glyoxylate shunt pathway, giving a net carbon gain. It plays a key role in the persistence of Mycobacterium tuberculosis within humans.
