molecular function |
| GO:0051287 | | NAD binding | | Interacting selectively and non-covalently with nicotinamide adenine dinucleotide, a coenzyme involved in many redox and biosynthetic reactions; binding may be to either the oxidized form, NAD+, or the reduced form, NADH. |
| GO:0070403 | | NAD+ binding | | Interacting selectively and non-covalently with the oxidized form, NAD, of nicotinamide adenine dinucleotide, a coenzyme involved in many redox and biosynthetic reactions. |
| GO:0070404 | | NADH binding | | Interacting selectively and non-covalently with the reduced form, NADH, of nicotinamide adenine dinucleotide, a coenzyme involved in many redox and biosynthetic reactions. |
| GO:0070401 | | NADP+ binding | | Interacting selectively and non-covalently with the oxidized form, NADP+, of nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions. |
| GO:0070402 | | NADPH binding | | Interacting selectively and non-covalently with the reduced form, NADPH, of nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions. |
| GO:0070405 | | ammonium ion binding | | Interacting selectively and non-covalently with ammonium ions (NH4+). |
| GO:0070406 | | glutamine binding | | Interacting selectively and non-covalently with glutamine, 2,5-diamino-5-oxopentanoic acid. |
| 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: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). |
biological process |
| GO:0045892 | | negative regulation of transcription, DNA-templated | | Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription. |
| GO:0090295 | | nitrogen catabolite repression of transcription | | A transcription regulation process in which the presence of one nitrogen source leads to a decrease in the frequency, rate, or extent of transcription of specific genes involved in the metabolism of other nitrogen sources. |
| GO:0001081 | | nitrogen catabolite repression of transcription from RNA polymerase II promoter | | A transcription regulation process in which the presence of one nitrogen source leads to a decrease in the frequency, rate, or extent of transcription, from an RNA polymerase II promoter, of specific genes involved in the metabolism of other nitrogen sources. |
| 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:0006808 | | regulation of nitrogen utilization | | Any process that modulates the frequency, rate or extent of nitrogen utilization. |
| GO:0006355 | | regulation of transcription, DNA-templated | | Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. |
| GO:0006351 | | transcription, DNA-templated | | The cellular synthesis of RNA on a template of DNA. |
cellular component |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
