WebApr 13, 2024 · The Rhodococcus erythropolis (strain IGTS8) bacterium has a tremendous industrial interest as it can remove sulfur from crude oil through its four-enzyme (DszA-D) 4S metabolic pathway. DszC is one of the rate-limiting enzymes of the pathway and the one that most suffers from feedback inhibition. We have combined molecular docking and … A diffusion-limited enzyme catalyses a reaction so efficiently that the rate limiting step is that of substrate diffusion into the active site, or product diffusion out. This is also known as kinetic perfection or catalytic perfection. Since the rate of catalysis of such enzymes is set by the diffusion-controlled reaction, it therefore represents an intrinsic, physical constraint on evolution (a maximum peak heig…
