molecular function |
| GO:0003973 | | (S)-2-hydroxy-acid oxidase activity | | Catalysis of the reaction: (S)-2-hydroxy-acid + O2 = 2-oxo acid + hydrogen peroxide. |
| GO:0010181 | | FMN binding | | Interacting selectively and non-covalently with flavin mono nucleotide. Flavin mono nucleotide (FMN) is the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes. |
| GO:0003824 | | catalytic activity | | Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic. |
| GO:0052853 | | long-chain-(S)-2-hydroxy-long-chain-acid oxidase activity | | Catalysis of the reaction: long-chain-(S)-2-hydroxy-acid + O2 = long-chain-2-oxo acid + hydrogen peroxide. Long chain refers to a chain length of 14 to 18 carbons. |
| GO:0052854 | | medium-chain-(S)-2-hydroxy-acid oxidase activity | | Catalysis of the reaction: medium-chain-(S)-2-hydroxy-acid + O2 = medium-chain-2-oxo acid + hydrogen peroxide. Medium chain refers to a chain length of between 8 and 12 carbons. |
| GO:0016491 | | oxidoreductase activity | | Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. |
| GO:0052852 | | very-long-chain-(S)-2-hydroxy-acid oxidase activity | | Catalysis of the reaction: very-long-chain (S)-2-hydroxy-acid + O2 = very-long-chain 2-oxo acid + hydrogen peroxide. Very long chain refers to a chain length of greater than 18 carbons. |
biological process |
| GO:0055114 | | oxidation-reduction process | | A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons. |
| GO:0009854 | | oxidative photosynthetic carbon pathway | | The reactions of the C2 pathway bring about the metabolic conversion of two molecules of 2-phosphoglycolate to one molecule of 3-phosphoglycerate, which can be used by the C3 cycle, and one molecule of carbon dioxide (CO2). |
| GO:0009853 | | photorespiration | | A light-dependent catabolic process occurring concomitantly with photosynthesis in plants (especially C3 plants) whereby dioxygen (O2) is consumed and carbon dioxide (CO2) is evolved. The substrate is glycolate formed in large quantities in chloroplasts from 2-phosphoglycolate generated from ribulose 1,5-bisphosphate by the action of ribulose-bisphosphate carboxylase; the glycolate enters the peroxisomes where it is converted by glycolate oxidase to glyoxylate which undergoes transamination to glycine. This then passes into the mitochondria where it is decarboxylated forming one molecule of serine for every two molecules of glycine. This pathway also exists in photosynthetic bacteria. |
cellular component |
| GO:0005777 | | peroxisome | | A small organelle enclosed by a single membrane, and found in most eukaryotic cells. Contains peroxidases and other enzymes involved in a variety of metabolic processes including free radical detoxification, lipid catabolism and biosynthesis, and hydrogen peroxide metabolism. |
