| Common Name | Allocystathionine |
|---|
| Description | Allocystathionine belongs to the class of organic compounds known as cysteines and cysteine derivatives. Cysteine and cysteine derivatives are compounds containing cysteine or a derivative thereof resulting from the reaction of cysteine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Allocystathionine is a stereo-isomer of cystathionine. Both cystathionine and allocystathionine are modified amino acids generated by enzymic means from homocysteine and serine. Allocystathionine is a product of enzyme cystathionine synthetase (EC 2.5.1.48) Which converts homocysteine into allocystathionine in the sulfur metabolism pathway. It is also the substrate of enzyme cystathionine beta-lyase (EC 4.4.1.8) In the same pathway (KEGG). Cystathionine and allocystathionine can be used by the enzymes cystathionine gamma-lyase (CTH), cysteine dioxygenase (CDO), and sulfinoalanine decarboxylase to produce hypotaurine and then taurine. |
