General description

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.

Application

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

Biochem/physiol Actions

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-lactic dehydrogenase catalyzes the conversion of L-lactate into L-pyruvate while reducing NAD+ to NADH and H+.

Unit Definition

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