CC to the respiratory chain. {ECO:0000255|HAMAP-Rule:MF_01559}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(S)-lactate + A = AH2 + pyruvate; Xref=Rhea:RHEA:45816,
CC ChEBI:CHEBI:13193, ChEBI:CHEBI:15361, ChEBI:CHEBI:16651,
CC ChEBI:CHEBI:17499; Evidence={ECO:0000255|HAMAP-Rule:MF_01559};
CC -!- COFACTOR:
CC Name=FMN; Xref=ChEBI:CHEBI:58210;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01559};
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01559}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01559}.
CC -!- SIMILARITY: Belongs to the FMN-dependent alpha-hydroxy acid
CC dehydrogenase family. {ECO:0000255|HAMAP-Rule:MF_01559}.
