CC -!- FUNCTION: Catalyzes the conversion of lactate to pyruvate (Potential).
CC Contributes to S.aureus growth during nitrosative stress in both
CC aerobically and anaerobically cultured cells, despite playing a
CC secondary role in this resistance mechanism (By similarity).
CC {ECO:0000250|UniProtKB:Q5HCV0, ECO:0000255|HAMAP-Rule:MF_00488}.
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:0000255|HAMAP-Rule:MF_00488};
CC -!- PATHWAY: Fermentation; pyruvate fermentation to lactate; (S)-lactate
CC from pyruvate: step 1/1. {ECO:0000255|HAMAP-Rule:MF_00488}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_00488}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00488}.
CC -!- SIMILARITY: Belongs to the LDH/MDH superfamily. LDH family.
