| molecular function |
|---|
| | GO:0080146 | | L-cysteine desulfhydrase activity | | Catalysis of the reaction: L-cysteine + H2O = ammonia + pyruvate + hydrogen sulfide + H+. |
| | 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:0004124 | | cysteine synthase activity | | Catalysis of the reaction: O3-acetyl-L-serine + hydrogen sulfide = L-cysteine + acetate. |
| | 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. |
| biological process |
|---|
| | GO:0008652 | | cellular amino acid biosynthetic process | | The chemical reactions and pathways resulting in the formation of amino acids, organic acids containing one or more amino substituents. |
| | GO:0019344 | | cysteine biosynthetic process | | The chemical reactions and pathways resulting in the formation of cysteine, 2-amino-3-mercaptopropanoic acid. |
| | GO:0006535 | | cysteine biosynthetic process from serine | | The chemical reactions and pathways resulting in the formation of cysteine from other compounds, including serine. |
| | 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. |
| cellular component |
|---|
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
