Lactate Dehydrogenase

Lactate Dehydrogenase (LDH), which catalyzes the inter-conversion of pyruvate and lactate.

Mammalian lactate dehydrogenase (LDH) comprises three major families of conserved enzymes that catalyse the reversible interconversion of pyruvate and lactate, a key metabolic step in glycolysis and other metabolic pathways. At least five LDH tetrameric isozymes are reported in somatic mammalian tissues, comprising LDHA and LDHB subunits, whereas LDHC4 is found only in mature testis and spermatozoa, where it is required for male fertility. Lactate dehydrogenase catalyzes the interconversion of pyruvate and lactate with concomitant interconversion of NADH and NAD+. At high concentrations of lactate, the enzyme exhibits feedback inhibition, and the rate of conversion of pyruvate to lactate is decreased. Dihydroorotate dehydrogenase (DHODH) is a key enzyme that catalyzes the oxidation of dihydroorotate (DHO) to produce orotate, a key step in pyrimidine biosynthesis.
