| FUNCTION | Catalyzes the alpha,beta-elimination reaction of D-cysteine and of several D-cysteine derivatives. It could be a defense mechanism against D-cysteine. |
| CATALYTIC ACTIVITY | Reaction=D-cysteine + H2O = hydrogen sulfide + pyruvate + NH4(+) + H(+); Xref=Rhea:RHEA:11268, ChEBI:CHEBI:15361, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:28938, ChEBI:CHEBI:29919, ChEBI:CHEBI:35236; EC=4.4.1.15; |
| case <FT:1> | |
| COFACTOR | Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326; |
| end case | |
| SUBUNIT | Homodimer. |
| SIMILARITY | Belongs to the ACC deaminase/D-cysteine desulfhydrase family. |
