molecular function |
| GO:0080146 | | L-cysteine desulfhydrase activity | | Catalysis of the reaction: L-cysteine + H2O = ammonia + pyruvate + hydrogen sulfide + H+. |
| GO:0016830 | | carbon-carbon lyase activity | | Catalysis of the cleavage of C-C bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. |
| 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:0042802 | | identical protein binding | | Interacting selectively and non-covalently with an identical protein or proteins. |
| 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:0030955 | | potassium ion binding | | Interacting selectively and non-covalently with potassium (K+) ions. |
| 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:0009034 | | tryptophanase activity | | Catalysis of the reaction: L-tryptophan + H(2)O = indole + NH(4)(+) + pyruvate. |
biological process |
| GO:0009072 | | aromatic amino acid family metabolic process | | The chemical reactions and pathways involving aromatic amino acid family, amino acids with aromatic ring (phenylalanine, tyrosine, tryptophan). |
| GO:0006520 | | cellular amino acid metabolic process | | The chemical reactions and pathways involving amino acids, carboxylic acids containing one or more amino groups, as carried out by individual cells. |
| GO:0006569 | | tryptophan catabolic process | | The chemical reactions and pathways resulting in the breakdown of tryptophan, the chiral amino acid 2-amino-3-(1H-indol-3-yl)propanoic acid. |
| GO:0006568 | | tryptophan metabolic process | | The chemical reactions and pathways involving tryptophan, the chiral amino acid 2-amino-3-(1H-indol-3-yl)propanoic acid. |
cellular component |
| GO:0060187 | | cell pole | | Either of two different areas at opposite ends of an axis of a cell. |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
