Description D-cysteine desulfhydrase
Notes A family of bacterial and plant enzymes, strictly related to L-cysteate sulfo-lyases (EC and to 1-aminocyclopropane-1-carboxylate deaminase (EC

Ser/Thr288 and Thr315 (numbering after the reference sequence from E. coli; the corresponding residues in the Solanum lycopersicon enzyme are Ser358 and Thr386, respectively) have been described by Todorovic and Glick as distinctive residues.
