In biochemistry, an oxidoreductase is an enzyme that catalyzes the transfer of electrons from one molecule, the reductant, also called the electron donor, to another, the oxidant, also called the electron acceptor.

Reductases are dehydrogenases which transfer hydrogen from the substrate to biological acceptors and to dyes. The assay of reductase is chiefly used in food chemistry to determine the freshness of milk. In pure cultures such as of lactic acid bacilli, the assay is also used to detect compounds that inhibit the bacterial growth.

谷胱甘肽还原酶(gluathione reductase)是人体 氧化还原 体系中最为重要的酶之一，是维持细胞中 还原型谷胱甘肽 （GSH）含量的主要 黄素酶 。 在 NADPH 参与下， 氧化型谷胱甘肽 转化为还原型谷胱甘肽，后者在防止 血红蛋白 的 氧化分解 、维持 巯基 蛋白的活性 ...

Ribonucleotide reductases (RNRs) catalyze the de novo conversion of nucleotides to deoxynucleotides in all organisms, controlling their relative ratios and abundance and in doing so play an important role in fidelity of DNA replication and repair.

Apr 28, 2014 · Ribonucleotide reductase (RNR) is a key enzyme that mediates the synthesis of deoxyribonucleotides, the DNA precursors, for DNA synthesis in every living cell. This enzyme converts ribonucleotides to deoxyribonucleotides, the building blocks for …

May 28, 2023 · (Science: enzyme) An enzyme that catalyses a reduction; since all enzymes catalyze reactions in either direction, any reductase can, under the proper conditions, behave as an oxidase and vice versa, hence the term oxidoreductase. For individual reductase’s, see the specific names. Synonym: reducing enzyme. You will also like...

Jun 15, 2023 · Carboxylic acid reductases (CARs) are large, multi-domain proteins that can catalyze the reduction of carboxylic acids to corresponding aldehydes, with the presence of adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate (NADPH).

reductase，英语单词，主要用作名词，作名词时译为“ [生化] 还原酶”。

Reductases are dehydrogenases (predominantly flavin enzymes) which transfer hydrogen from the substrate to biological acceptors and to dyes. The assay of reductase is chiefly used in food chemistry to determine the freshness (bacterial content) of milk 1).
