Probing the Human 4-Oxo- l -proline Reductase-Catalyzed Reaction by Deuterium Kinetic and Equilibrium Isotope Effects
Ennio Pečaver, Myriam Kabu, Greice Michele Zickuhr, David J. Harrison et autres
Human 4-oxo-l-proline reductase (HsBDH2), a short-chain dehydrogenase/reductase (SDR) superfamily member possessing a canonical N-S-Y-K catalytic tetrad, catalyzes the formation of the endogenous anticancer compound cis-4-hydroxy-l-proline via the NADH-dependent reduction of 4-oxo-l-proline. Except for hydride-transfer stereochemistry, information on the HsBDH2 chemical step remains …
