Abstract

Pentaerythritol tetranitrate reductase, which reductively liberates nitrite from nitrate esters, is related to old yellow enzyme. Pentaerythritol tetranitrate reductase follows a ping-pong mechanism with competitive substrate inhibition by NADPH, is strongly inhibited by steroids, and is capable of reducing the unsaturated bond of 2-cyclohexen-1-one.

摘要

季戊四醇四硝酸酯还原酶可从硝酸酯中还原释放出亚硝酸盐,它与老黄色酶相关。季戊四醇四硝酸酯还原酶遵循乒乓机制,受NADPH竞争性底物抑制,受类固醇强烈抑制,并且能够还原2-环己烯-1-酮的不饱和键。
