IPR005966 is a D-cysteine desulfhydrase.
<p>This entry represents a family of pyridoxal phosphate-dependent enzymes closely related to (and often designated as putative examples of) 1-aminocyclopropane-1-carboxylate deaminase. Members of this family include D-cysteine desulfhydrase ([ec:4.4.1.15]) , 1-aminocyclopropane-1-carboxylate deaminase ([ec:3.5.99.7]), and L-cysteate sulfo-lyase ([ec:4.4.1.25]).</p> <p>1-aminocyclopropane-1-carboxylate deaminase ([ec:3.5.99.7]) catalyses a cyclopropane ring-opening reaction, the irreversible conversion of 1-aminocyclopropane-1-carboxylate (ACC) to ammonia and alpha-ketobutyrate [[cite:PUB00063667]]. Some plant growth-promoting rhizobacteria can produce 1-aminocyclopropane-1-carboxylate deaminase to enhance plant growth [[cite:PUB00063668], [cite:PUB00063669]].</p> <p>D-cysteine desulfhydrase (d-CDes) ([ec:4.4.1.15]) catalyses the alpha, beta-elimination reaction of D-cysteine and of several D-cysteine derivatives. The Escherichia coli d-CDes catalyses D-cysteine into pyruvate, H2S, and NH3 [[cite:PUB00063672], [cite:PUB00063671], [cite:PUB00063670]]. The physiological function of bacterial d-CDes is not clear.</p>

GO predictions are based solely on the InterPro-to-GO mappings published by EMBL-EBI, which are in turn based on the mapping of predicted domains to the InterPro dataset. The InterPro-to-GO mapping was last updated on , while the GO metadata was last updated on .

| Molecular function | Catalytic activity | Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic. |
