cysteine desulfhydrase a
Activity cysteine_desulfhydrase
Description Cysteine desulfhydrase (4.4.1.-). (family a)
Notes All the characterized enzymes in this family also show cystathionine beta-lyase activity (E.C. and sometimes methionine gamma-lyase activity (
Indeed, the family is tightly related to families and, with which it forms a 'supercluster' of C-S lyase enzymes.
