molecular function |
| GO:0051537 | | 2 iron, 2 sulfur cluster binding | | Interacting selectively and non-covalently with a 2 iron, 2 sulfur (2Fe-2S) cluster; this cluster consists of two iron atoms, with two inorganic sulfur atoms found between the irons and acting as bridging ligands. |
| GO:0008942 | | nitrite reductase [NAD(P)H] activity | | Catalysis of the reaction: ammonium hydroxide + 3 NAD(P)+ + H2O = nitrite + 3 NAD(P)H + 3 H+. |
| 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. |
biological process |
| GO:0009061 | | anaerobic respiration | | The enzymatic release of energy from inorganic and organic compounds (especially carbohydrates and fats) which uses compounds other than oxygen (e.g. nitrate, sulfate) as the terminal electron acceptor. |
| GO:0042128 | | nitrate assimilation | | The nitrogen metabolic process that encompasses the uptake of nitrate from the environment and reduction to ammonia, and results in the incorporation of nitrogen derived from nitrate into cellular substances. |
| 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. |
cellular component |
| GO:0009344 | | nitrite reductase complex [NAD(P)H] | | Complex that possesses nitrite reductase [NAD(P)H] activity. |
