| molecular function |
|---|
| | GO:0003870 | | 5-aminolevulinate synthase activity | | Catalysis of the reaction: glycine + H(+) + succinyl-CoA = 5-aminolevulinate + CO(2) + CoA. |
| | 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:0030170 | | pyridoxal phosphate binding | | Interacting selectively and non-covalently with pyridoxal 5' phosphate, 3-hydroxy-5-(hydroxymethyl)-2-methyl4-pyridine carboxaldehyde 5' phosphate, the biologically active form of vitamin B6. |
| | GO:0016740 | | transferase activity | | Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2. |
| | GO:0016746 | | transferase activity, transferring acyl groups | | Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor). |
| biological process |
|---|
| | GO:0009058 | | biosynthetic process | | The chemical reactions and pathways resulting in the formation of substances; typically the energy-requiring part of metabolism in which simpler substances are transformed into more complex ones. |
| | 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:0030218 | | erythrocyte differentiation | | The process in which a myeloid precursor cell acquires specializes features of an erythrocyte. |
| | 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:0042541 | | hemoglobin biosynthetic process | | The chemical reactions and pathways resulting in the formation of hemoglobin, an oxygen carrying, conjugated protein containing four heme groups and globin. |
| | GO:0008152 | | metabolic process | | The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation. |
| | GO:0006778 | | porphyrin-containing compound metabolic process | | The chemical reactions and pathways involving any member of a large group of derivatives or analogs of porphyrin. Porphyrins consists of a ring of four pyrrole nuclei linked each to the next at their alpha positions through a methine group. |
| | GO:0006782 | | protoporphyrinogen IX biosynthetic process | | The chemical reactions and pathways resulting in the formation of protoporphyrinogen IX. |
| | GO:0001666 | | response to hypoxia | | 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 indicating lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level. |
| | GO:0033014 | | tetrapyrrole biosynthetic process | | The chemical reactions and pathways leading to the formation of tetrapyrroles, natural pigments containing four pyrrole rings joined by one-carbon units linking position 2 of one pyrrole ring to position 5 of the next. |
| 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: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. |
