Protein: L-lactate dehydrogenase (cytochrome) (EC 1.1.2.3) (Cytochrome b2) (Flavocytochrome b2) (FCB2) (L-lactate ferricytochrome c oxidoreductase) (L-LCR) (P00175)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: Catalyzes the oxidation of (S)-lactate (L-lactate) to pyruvate with subsequent transfer of electrons to cytochrome c. Is involved in the utilization of (S)-lactate as a sole source of carbon for growth. Can also use ferricyanide as an electron acceptor in vitro.
Subcellular location: Mitochondrion intermembrane space {ECO:0000269|PubMed:11502169, ECO:0000269|PubMed:22984289}.
