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:0008750 | | NAD(P)+ transhydrogenase (AB-specific) activity | | Catalysis of the reaction: NADPH + H+ + NAD+ = NADP+ + NADH + H+. The reaction is A-specific (i.e. the pro-R hydrogen is transferred from the 4-position of reduced nicotinamide cofactor) with respect to NAD+ and B-specific (i.e. the pro-S hydrogen is transferred) with respect to NADP+. |
| GO:0008746 | | NAD(P)+ transhydrogenase activity | | Catalysis of the reaction: NADPH + H+ + NAD+ = NADP+ + NADH + H+. |
| GO:0050661 | | NADP binding | | Interacting selectively and non-covalently with nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions; binding may be to either the oxidized form, NADP+, or the reduced form, NADPH. |
| 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:0006740 | | NADPH regeneration | | A metabolic process that generates a pool of NADPH by the reduction of NADP+. |
| GO:0045454 | | cell redox homeostasis | | Any process that maintains the redox environment of a cell or compartment within a cell. |
| 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:0015992 | | proton transport | | The directed movement of protons (hydrogen ions) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| GO:0072593 | | reactive oxygen species metabolic process | | The chemical reactions and pathways involving a reactive oxygen species, any molecules or ions formed by the incomplete one-electron reduction of oxygen. They contribute to the microbicidal activity of phagocytes, regulation of signal transduction and gene expression, and the oxidative damage to biopolymers. |
cellular component |
| GO:0016021 | | integral component of membrane | | The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
| GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| GO:0005743 | | mitochondrial inner membrane | | The inner, i.e. lumen-facing, lipid bilayer of the mitochondrial envelope. It is highly folded to form cristae. |
| GO:0005739 | | mitochondrion | | A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration. |
