molecular function |
| 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:0004586 | | ornithine decarboxylase activity | | Catalysis of the reaction: L-ornithine + H(+) = CO(2) + putrescine. |
| GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| GO:0042803 | | protein homodimerization activity | | Interacting selectively and non-covalently with an identical protein to form a homodimer. |
biological process |
| GO:0001822 | | kidney development | | The process whose specific outcome is the progression of the kidney over time, from its formation to the mature structure. The kidney is an organ that filters the blood and/or excretes the end products of body metabolism in the form of urine. |
| GO:0006596 | | polyamine biosynthetic process | | The chemical reactions and pathways resulting in the formation of polyamines, any organic compound containing two or more amino groups. |
| GO:0006595 | | polyamine metabolic process | | The chemical reactions and pathways involving polyamines, any organic compound containing two or more amino groups. |
| GO:0008284 | | positive regulation of cell proliferation | | Any process that activates or increases the rate or extent of cell proliferation. |
| GO:0009446 | | putrescine biosynthetic process | | The chemical reactions and pathways resulting in the formation of putrescine, 1,4-diaminobutane; putrescine can be synthesized from arginine or ornithine and is the metabolic precursor of spermidine and spermine. |
| GO:0033387 | | putrescine biosynthetic process from ornithine | | The chemical reactions and pathways resulting in the formation of putrescine, 1,4-diaminobutane by decarboxylation of ornithine. |
| GO:0006521 | | regulation of cellular amino acid metabolic process | | Any process that modulates the frequency, rate or extent of the chemical reactions and pathways involving amino acids. |
| GO:0042176 | | regulation of protein catabolic process | | Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the breakdown of a protein by the destruction of the native, active configuration, with or without the hydrolysis of peptide bonds. |
| GO:0009615 | | response to virus | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus from a virus. |
cellular component |
| GO:0005575 | | cellular_component | | The part of a cell, extracellular environment or virus in which a gene product is located. A gene product may be located in one or more parts of a cell and its location may be as specific as a particular macromolecular complex, that is, a stable, persistent association of macromolecules that function together. |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| GO:0048471 | | perinuclear region of cytoplasm | | Cytoplasm situated near, or occurring around, the nucleus. |
