| molecular function |
| | GO:0033982 | | 3-dehydro-L-gulonate-6-phosphate decarboxylase activity | | Catalysis of the reaction: 3-dehydro-L-gulonate 6-phosphate + H(+) = L-xylulose 5-phosphate + CO(2). |
| | GO:0016831 | | carboxy-lyase activity | | Catalysis of the nonhydrolytic addition or removal of a carboxyl group to or from a compound. |
| | 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:0016829 | | lyase activity | | Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring. |
| | GO:0000287 | | magnesium ion binding | | Interacting selectively and non-covalently with magnesium (Mg) ions. |
| | GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| | GO:0004590 | | orotidine-5'-phosphate decarboxylase activity | | Catalysis of the reaction: H(+) + orotidine 5'-phosphate = CO(2) + UMP. |
| biological process |
| | GO:0006207 | | 'de novo' pyrimidine nucleobase biosynthetic process | | The chemical reactions and pathways resulting in the formation of pyrimidine nucleobases, 1,3-diazine, organic nitrogenous bases, beginning with the synthesis of a pyrimidine ring from simpler precursors. |
| | GO:0019854 | | L-ascorbic acid catabolic process | | The chemical reactions and pathways resulting in the breakdown of L-ascorbic acid; L-ascorbic acid ionizes to give L-ascorbate, (2R)-2-[(1S)-1,2-dihydroxyethyl]-4-hydroxy-5-oxo-2,5-dihydrofuran-3-olate, which is required as a cofactor in the oxidation of prolyl residues to hydroxyprolyl, and other reactions. |
| | GO:0005975 | | carbohydrate metabolic process | | The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule. |
| | GO:0008152 | | metabolic process | | The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation. |
