Description L-cysteate sulfo-lyase
Alternative names L-cysteate sulfo-lyase (deaminating);
CuyA.
Catalyzed reaction L-cysteate + H2O = pyruvate + bisulfite + NH3
Cofactor Pyridoxal-phosphate.
Comments A pyridoxal-phosphate protein. D-Cysteine can also act as a substrate, but more slowly. It is converted into pyruvate, sulfide and NH3. This inducible enzyme from the marine bacterium Silicibacter pomeroyi DSS-3 forms part of the cysteate-degradation pathway.
