CC -!- FUNCTION: A cysteine desulfhydrase that generates hydrogen sulfide,
CC H(2)S. The H(2)S produced by this enzyme may modulate central
CC metabolism. {ECO:0000256|HAMAP-Rule:MF_00868}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + L-cysteine = H(+) + hydrogen sulfide + NH4(+) +
CC pyruvate; Xref=Rhea:RHEA:24931, ChEBI:CHEBI:15361, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:28938, ChEBI:CHEBI:29919,
CC ChEBI:CHEBI:35235; EC=4.4.1.1; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_00868};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|ARBA:ARBA00001933,
CC ECO:0000256|HAMAP-Rule:MF_00868};
CC -!- SIMILARITY: Belongs to the cysteine synthase/cystathionine beta-
CC synthase family. Cds1 subfamily. {ECO:0000256|HAMAP-Rule:MF_00868}.
