B6db activities: cysteine.desulfhydrase

cysteine_desulfhydrase
Description Cysteine desulfhydrase (4.4.1.-).
Alternative names C-S lyase (ambiguous).
Catalyzed reaction L-Cysteine + H(2)O = pyruvate + H(2)S + NH(3)
Cofactor Pyridoxal-phosphate.
The validated enzymes that catalyze this reaction also show cystathionine beta-lyase activity (E.C. 4.4.1.8) and sometimes methionine gamma-lyase activity (4.4.1.11).
PDB 1C7O;
Organisms -Eubacteria
