Citation | Journal: Nature / Year: 2019 Title: An allosteric mechanism for potent inhibition of human ATP-citrate lyase. Authors: Jia Wei / Silvana Leit / Jun Kuai / Eric Therrien / Salma Rafi / H James Harwood / Byron DeLaBarre / Liang Tong / Abstract: ATP-citrate lyase (ACLY) is a central metabolic enzyme and catalyses the ATP-dependent conversion of citrate and coenzyme A (CoA) to oxaloacetate and acetyl-CoA. The acetyl-CoA product is crucial for ...ATP-citrate lyase (ACLY) is a central metabolic enzyme and catalyses the ATP-dependent conversion of citrate and coenzyme A (CoA) to oxaloacetate and acetyl-CoA. The acetyl-CoA product is crucial for the metabolism of fatty acids, the biosynthesis of cholesterol, and the acetylation and prenylation of proteins. There has been considerable interest in ACLY as a target for anti-cancer drugs, because many cancer cells depend on its activity for proliferation. ACLY is also a target against dyslipidaemia and hepatic steatosis, with a compound currently in phase 3 clinical trials. Many inhibitors of ACLY have been reported, but most of them have weak activity. Here we report the development of a series of low nanomolar, small-molecule inhibitors of human ACLY. We have also determined the structure of the full-length human ACLY homo-tetramer in complex with one of these inhibitors (NDI-091143) by cryo-electron microscopy, which reveals an unexpected mechanism of inhibition. The compound is located in an allosteric, mostly hydrophobic cavity next to the citrate-binding site, and requires extensive conformational changes in the enzyme that indirectly disrupt citrate binding. The observed binding mode is supported by and explains the structure-activity relationships of these compounds. This allosteric site greatly enhances the 'druggability' of ACLY and represents an attractive target for the development of new ACLY inhibitors. | |||||||||||||||
