molecular function |
| GO:0043857 | | N-acetylornithine carbamoyltransferase activity | | Catalysis of the reaction: N(2)-acetyl-L-ornithine + carbamoyl phosphate = N(2)-acetyl-L-citrulline + H(+) + phosphate. |
| GO:0016597 | | amino acid binding | | Interacting selectively and non-covalently with an amino acid, organic acids containing one or more amino substituents. |
| GO:0004070 | | aspartate carbamoyltransferase activity | | Catalysis of the reaction: L-aspartate + carbamoyl phosphate = N-carbamoyl-L-aspartate + H(+) + phosphate. |
| GO:0016743 | | carboxyl- or carbamoyltransferase activity | | Catalysis of the transfer of a carboxyl- or carbamoyl group from one compound (donor) to another (acceptor). |
| GO:0004585 | | ornithine carbamoyltransferase activity | | Catalysis of the reaction: carbamoyl phosphate + L-ornithine = phosphate + L-citrulline. |
| GO:0016740 | | transferase activity | | Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2. |
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:0006526 | | arginine biosynthetic process | | The chemical reactions and pathways resulting in the formation of arginine, 2-amino-5-(carbamimidamido)pentanoic acid. |
| GO:0042450 | | arginine biosynthetic process via ornithine | | The chemical reactions and pathways resulting in the formation of arginine (2-amino-5-guanidinopentanoic acid) via the intermediate compound ornithine. |
| GO:0008652 | | cellular amino acid biosynthetic process | | The chemical reactions and pathways resulting in the formation of amino acids, organic acids containing one or more amino substituents. |
| GO:0006520 | | cellular amino acid metabolic process | | The chemical reactions and pathways involving amino acids, carboxylic acids containing one or more amino groups, as carried out by individual cells. |
| GO:0000050 | | urea cycle | | The sequence of reactions by which arginine is synthesized from ornithine, then cleaved to yield urea and regenerate ornithine. The overall reaction equation is NH3 + CO2 + aspartate + 3 ATP + 2 H2O = urea + fumarate + 2 ADP + 2 phosphate + AMP + diphosphate. |
cellular component |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
