一般描述

LDH (lactic dehydrogenase), a glycolytic enzyme, particularly present in skeletal muscle, heart, liver, kidneys, brain, lungs and red blood cells. It has five isoenzyme forms. LDH possess a tetrameric structure.

应用

Lactic Dehydrogenase, recombinant from E. coli has been used:

• in lactate dehydrogenase (LDH) and malate dehydrogenase 1 (MDH1)assays and cross-linking assays
• to prepare assay buffer to measure pyruvate kinase (PYK) by coupled assay
• in in vitro DltC D-alanylation assay

生化/生理作用

Conversion of L-lactate into L-pyruvate is crucial in hypoxic and anaerobic conditions, especially when synthesis of adenosine triphosphate (ATP) by oxidative phosphorylation is interrupted.
L -乳酸脱氢酶催化 L -乳酸转化为 L -丙酮酸，同时还原 NAD ⁺ 为 NADH 和 H ⁺ 。

单位定义

One unit corresponds to the amount of enzyme which reduces 1 μmol pyruvate per minute at pH 7.4 and 25℃ (NADH as cofactor)
