molecular function |
| 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:0031071 | | cysteine desulfurase activity | | Catalysis of the reaction: L-cysteine + [enzyme]-cysteine = L-alanine + [enzyme]-S-sulfanylcysteine. |
| GO:0016829 | | lyase activity | | Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring. |
| 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). |
| 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:0009000 | | selenocysteine lyase activity | | Catalysis of the reaction: L-selenocysteine + reduced acceptor = hydrogen selenide + L-alanine + acceptor. |
| 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. |
biological process |
| GO:0006534 | | cysteine metabolic process | | The chemical reactions and pathways involving cysteine, 2-amino-3-mercaptopropanoic acid. |
| GO:0016226 | | iron-sulfur cluster assembly | | The incorporation of iron and exogenous sulfur into a metallo-sulfur cluster. |
| GO:0001887 | | selenium compound metabolic process | | The chemical reactions and pathways involving compounds that contain selenium, such as selenocysteine. |
| GO:0006790 | | sulfur compound metabolic process | | The chemical reactions and pathways involving the nonmetallic element sulfur or compounds that contain sulfur, such as the amino acids methionine and cysteine or the tripeptide glutathione. |
| GO:0031162 | | sulfur incorporation into metallo-sulfur cluster | | The incorporation of exogenous sulfur into a metallo-sulfur cluster. |
cellular component |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
