CC -!- FUNCTION: Interconverts simultaneously and stereospecifically pyruvate
CC and lactate with concomitant interconversion of NADH and NAD(+).
CC {ECO:0000250|UniProtKB:P07195}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(S)-lactate + NAD(+) = H(+) + NADH + pyruvate;
CC Xref=Rhea:RHEA:23444, ChEBI:CHEBI:15361, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16651, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=1.1.1.27;
CC Evidence={ECO:0000250|UniProtKB:P07195};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:23445;
CC Evidence={ECO:0000250|UniProtKB:P07195};
CC PhysiologicalDirection=right-to-left; Xref=Rhea:RHEA:23446;
CC Evidence={ECO:0000250|UniProtKB:P07195};
CC -!- PATHWAY: Fermentation; pyruvate fermentation to lactate; (S)-lactate
CC from pyruvate: step 1/1. {ECO:0000250|UniProtKB:P07195}.
CC -!- SUBUNIT: Homotetramer. Interacts with PTEN upstream reading frame
CC protein MP31; the interaction leads to inhibition of mitochondrial
CC lactate dehydrogenase activity, preventing conversion of lactate to
CC pyruvate in mitochondria. {ECO:0000250|UniProtKB:P07195}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Mitochondrion inner
CC membrane {ECO:0000250|UniProtKB:P07195}; Peripheral membrane protein
CC {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the LDH/MDH superfamily. LDH family.
CC {ECO:0000305}.
