Description Cysteine lyase
Alternative names cysteine (sulfite) lyase;
L-cysteine hydrogen-sulfide-lyase (adding sulfite)
Catalyzed reaction L-cysteine + sulfite = L-cysteate + H(2)S.
Cofactor Pyridoxal-phosphate.
Comments -!- Can use a second molecule of cysteine (producing lanthionine) or other alkyl thiols as replacing agents.
Organisms -Metazoa
Links Enzyme (activities)
BRENDA (activities)
KEGG (pathways)
PLPMDB (PLP mutants)
