>cd05290 LDH_3 A subgroup of L-lactate dehydrogenases. L-lactate dehydrogenases (LDH) are tetrameric enzymes catalyzing the last step of glycolysis in which pyruvate is converted to L-lactate. This subgroup is composed of some bacterial LDHs from firmicutes, gammaproteobacteria, and actinobacteria. Vertebrate LDHs are non-allosteric, but some bacterial LDHs are activated by an allosteric effector such as fructose-1,6-bisphosphate. LDHs are part of the NAD(P)-binding Rossmann fold superfamily, which includes a wide variety of protein families including the NAD(P)-binding domains of alcohol dehydrogenases, tyrosine-dependent oxidoreductases, glyceraldehyde-3-phosphate dehydrogenases, formate/glycerate dehydrogenases, siroheme synthases, 6-phosphogluconate dehydrogenase, aminoacid dehydrogenases, repressor rex, and NAD-binding potassium channel domains, among others.
