CC   -!- FUNCTION: Catalyzes the alpha,beta-elimination reaction of D-cysteine
CC       and of several D-cysteine derivatives. It could be a defense mechanism
CC       against D-cysteine. {ECO:0000255|HAMAP-Rule:MF_01045}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-cysteine + H2O = H(+) + hydrogen sulfide + NH4(+) +
CC         pyruvate; Xref=Rhea:RHEA:11268, ChEBI:CHEBI:15361, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:28938, ChEBI:CHEBI:29919,

CC         Rule:MF_01045};
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01045};
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01045}.
CC   -!- SIMILARITY: Belongs to the ACC deaminase/D-cysteine desulfhydrase
CC       family. {ECO:0000255|HAMAP-Rule:MF_01045}.
