Method: X-ray diffraction, Resolution 1.9Å Ligands: FMN, PYR Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function LOX_AERVM Catalyzes the oxidation of (S)-lactate (L-lactate) to pyruvate, with a reduction of O2 to H2O2 (Ref.1, PubMed:27302031, PubMed:25423902, PubMed:2818595, PubMed:8589073, PubMed:26260739). Cannot oxidize D-lactate, glycolate, and D,L-2-hydroxybutanoate (PubMed:2818595). May be involved in the utilization of L-lactate as an energy source for growth (By similarity).[UniProtKB:O33655] [UniProtKB:O33655] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMed L-Lactate oxidase (LOX) from Aerococcus viridans catalyzes the oxidation of L-lactate to pyruvate by the molecular oxygen and belongs to a large family of 2-hydroxy acid-dependent flavoenzymes. To investigate the interaction of LOX with pyruvate in structural details and understand the chemical mechanism of flavin-dependent L-lactate dehydrogenation, the LOX-pyruvate complex was crystallized and the crystal structure of the complex has been solved at a resolution of 1.90 Angstrom. One pyruvate molecule bound to the active site and located near N5 position of FMN for subunits, A, B, and D in the asymmetric unit, were identified. The pyruvate molecule is stabilized by the interaction of its carboxylate group with the side-chain atoms of Tyr40, Arg181, His265, and Arg268, and of its keto-oxygen atom with the side-chain atoms of Tyr146, Tyr215, and His265. The alpha-carbon of pyruvate is found to be 3.13 Angstrom from the N5 atom of FMN at an angle of 105.4 degrees from the flavin N5-N10 axis.
