What the D-cysteine is?
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 , 1-aminocyclopropane-1-carboxylate deaminase , and L-cysteate sulfo-lyase.
1-aminocyclopropane-1-carboxylate deaminase catalyses a cyclopropane ring-opening reaction, the irreversible conversion of 1-aminocyclopropane-1-carboxylate to ammonia and alpha-ketobutyrate. Some plant growth-promoting rhizobacteria can produce 1-aminocyclopropane-1-carboxylate deaminase to enhance plant growth.
D-cysteine desulfhydrase 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. The physiological function of bacterial d-CDes is not clear.
