4.4.1.8
Description Cystathionine beta-lyase
Alternative names Beta-cystathionase;
Beta C-S lyase;
Cysteine lyase;
Cystine lyase.
Catalyzed reaction Cystathionine + H(2)O = L-homocysteine + NH(3) + pyruvate.
Cofactor Pyridoxal-phosphate.
Comments -!- The enzyme from some sources also acts on L-cystine, forming pyruvate, ammonia and cysteine persulfide, and a number of related compounds.
-!- Possibly identical, in yeast, with EC 4.4.1.6.
In some organisms, such as Lactococcus lactis, this activity is carried out by an enzyme that also possesses a gamma-lyase activity (EC 4.4.1.1) and that is very similar to cystathionine gamma-lyases in terms of sequence.
