THE STRUCTURE OF F1-ATPASE INHIBITED BY QUERCETIN.
Overview
The structures of F(1)-ATPase from bovine heart mitochondria inhibited, with the dietary phytopolyphenol, resveratrol, and with the related, polyphenols quercetin and piceatannol have been determined at 2.3-, 2.4-, and 2.7-A resolution, respectively. The inhibitors bind to a common site, in the inside surface of an annulus made from loops in the three alpha-, and three beta-subunits beneath the "crown" of beta-strands in their, N-terminal domains. This region of F(1)-ATPase forms a bearing to allow, the rotation of the tip of the gamma-subunit inside the annulus during, catalysis. The binding site is a hydrophobic pocket between the C-terminal, tip of the gamma-subunit and the beta(TP) subunit, and the inhibitors are, bound via H-bonds mostly to their hydroxyl moieties mediated by bound, ...
