ENTRY       EC 4.4.1.10
NAME        Cysteine lyase
CLASS       Lyases
            Carbon-sulfur lyases
SYSNAME     L-Cysteine hydrogen-sulfide-lyase (adding sulfite)
REACTION    L-Cysteine + Sulfite = L-Cysteate + Sulfide
SUBSTRATE   L-Cysteine
            Sulfite
PRODUCT     L-Cysteate
            Sulfide
COFACTOR    Pyridoxal phosphate
COMMENT     A pyridoxal-phosphate protein. Can use a second molecule of
            cysteine (producing lanthionine) or other alkyl thiols as
            replacing agents.
