molecular function |
| GO:0016597 | | amino acid binding | | Interacting selectively and non-covalently with an amino acid, organic acids containing one or more amino substituents. |
| 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: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:0019547 | | arginine catabolic process to ornithine | | The chemical reactions and pathways resulting in the breakdown of arginine into other compounds, including ornithine. |
| GO:0019546 | | arginine deiminase pathway | | The chemical reactions and pathways resulting in the breakdown of arginine into other compounds, including ornithine and CO2, using the enzyme arginine deiminase. |
| GO:0006525 | | arginine metabolic process | | The chemical reactions and pathways involving arginine, 2-amino-5-(carbamimidamido)pentanoic acid. |
| 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:0006591 | | ornithine metabolic process | | The chemical reactions and pathways involving ornithine, an amino acid only rarely found in proteins, but which is important in living organisms as an intermediate in the reactions of the urea cycle and in arginine biosynthesis. |
| 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. |
