4.4.1.15	D-cysteine + H2O	-	
4.4.1.15	D-cysteine + H2O	plant sulfur metabolism	
4.4.1.15	D-cysteine + H2O	physiological function unknown, detoxification of D-cysteine suggested, contributes to utilization of D-cysteine as sulfur source	
4.4.1.15	additional information	extracellular production of hydrogen selenide accounts for thiol-assisted toxicity of selenite against Saccharomyces cerevisiae	
4.4.1.15	additional information	Site-directed mutagenesis shows that altering only two amino acid residues within the predicted active site served to change the enzyme from D-cysteine desulfhydrase to 1-aminocyclopropane-1-carboxylate deaminase.	
4.4.1.15	additional information	Site-directed mutagenesis shows that altering two amino acid residues at the same positions within the active site of tive site served to change the enzyme from D-cysteine desulfhydrase to deaminase from Pseudomonas putida UW4 the enzyme is converted into D-cysteine desulfhydrase.
