Abstract:ATP citrate lyase (ACL or ACLY) is an extra-mitochondrial enzyme widely distributed in various human and animal tissues. Although rodent studies suggested potential effects of ACL inhibition on both fatty acid and cholesterol synthesis, studies in humans show an effect only on cholesterol synthesis. inhibition correlates with the glycolytic phenotype of the tumor (12). ATP citrate lyase is an important enzyme for he fast dividing cancer cells ATP citrate lyase (ACL or ACLY) is an intracellular enzyme (located in cytosol) responsible for the conversion of citrate that comes out of the mitochondria, to acetyl-CoA and oxaloacetate. Hatzivassiliou G, et al. To date only partial X-ray structures of ACLY have been solved, thus limiting the design of novel inhibitors. Studies were performed with recombinant human ACL to ascertain the nature of the catalytic phosphorylation that initiates the ACL reaction and the identity of the active site residues involved.
