	4.4.1.25
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.
Organisms	-Bacteria
