4.1.1.29 |
| Description |
Sulfinoalanine decarboxylase. |
| Alternative names |
Cysteine-sulfinate decarboxylase;
Cysteine sulfinic acid decarboxylase;
CSADCase. |
| Catalyzed reaction |
3-sulfino-L-alanine = hypotaurine + CO(2). |
| Cofactor |
Pyridoxal-phosphate. |
| Comments |
-!- Also acts on l-cysteate. |
| |
The enzyme is involved in the biosynthesis of taurine, a sulfur-containing amino compound that apparently functions as a cytoprotectant and occurs at high concentration (5–50 mM) in most animal tissues.
The sequences of sulfinoalanine decarboxylases are strictly related to those of metazoan glutamate decarboxylases (4.1.1.15). |
