molecular function |
| GO:0008199 | | ferric iron binding | | Interacting selectively and non-covalently with ferric iron, Fe(III). |
| GO:0008198 | | ferrous iron binding | | Interacting selectively and non-covalently with ferrous iron, Fe(II). |
| GO:0004322 | | ferroxidase activity | | Catalysis of the reaction: 4 Fe2+ + 4 H+ + O2 = 4 Fe3+ + 2 H2O. |
| GO:0034986 | | iron chaperone activity | | Assists in the delivery of iron ions to target proteins or compartments. |
| 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:0006879 | | cellular iron ion homeostasis | | Any process involved in the maintenance of an internal steady state of iron ions at the level of a cell. |
| GO:0006749 | | glutathione metabolic process | | The chemical reactions and pathways involving glutathione, the tripeptide glutamylcysteinylglycine, which acts as a coenzyme for some enzymes and as an antioxidant in the protection of sulfhydryl groups in enzymes and other proteins; it has a specific role in the reduction of hydrogen peroxide (H2O2) and oxidized ascorbate, and it participates in the gamma-glutamyl cycle. |
| GO:0006783 | | heme biosynthetic process | | The chemical reactions and pathways resulting in the formation of heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring, from less complex precursors. |
| GO:0006811 | | ion transport | | The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| GO:0055072 | | iron ion homeostasis | | Any process involved in the maintenance of an internal steady state of iron ions within an organism or cell. |
| GO:0016226 | | iron-sulfur cluster assembly | | The incorporation of iron and exogenous sulfur into a metallo-sulfur cluster. |
| GO:0006121 | | mitochondrial electron transport, succinate to ubiquinone | | The transfer of electrons from succinate to ubiquinone that occurs during oxidative phosphorylation, mediated by the multisubunit enzyme known as complex II. |
| 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:0006626 | | protein targeting to mitochondrion | | The process of directing proteins towards and into the mitochondrion, usually mediated by mitochondrial proteins that recognize signals contained within the imported protein. |
| GO:0010040 | | response to iron(II) ion | | 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 an iron(II) ion stimulus. |
| GO:0006979 | | response to oxidative stress | | 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 oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals. |
| GO:0006810 | | transport | | The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein. |
cellular component |
| 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:0005758 | | mitochondrial intermembrane space | | The region between the inner and outer lipid bilayers of the mitochondrial envelope. |
| GO:0005759 | | mitochondrial matrix | | The gel-like material, with considerable fine structure, that lies in the matrix space, or lumen, of a mitochondrion. It contains the enzymes of the tricarboxylic acid cycle and, in some organisms, the enzymes concerned with fatty acid oxidation. |
| 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. |
