The crystal structure of lactate oxidase
Structural highlights
FunctionLOX_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][1] [2] [3] [4] [5] [UniProtKB:O33655] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe crystal structure of L-lactate oxidase (LOX) from Aerococcus viridans has been determined at 2.1 A resolution. LOX catalyzes the flavin mononucleotide (FMN) dependent oxidation of lactate to pyruvate and hydrogen peroxide. LOX belongs to the alpha-hydroxy-acid oxidase flavoenzyme family; members of which bind similar substrates and to some extent have conserved catalytic properties and structural motifs. LOX crystallized as two tightly packed tetramers in the asymmetric unit, each having fourfold symmetry. The present structure shows a conserved FMN coordination, but also reveals novel residues involved in substrate binding compared with other family members.
