|Beta C-S lyase.|
|L-cystathionine + H(2)O <=> L-homocysteine + NH(3) + pyruvate|
- The enzyme cleaves a carbon-sulfur bond, releasing L-homocysteine and
an unstable enamine product that tautomerizes to an imine form, which
undergoes a hydrolytic deamination to form pyruvate and ammonia.
- The latter reaction, which can occur spontaneously, can also be
catalyzed by EC 18.104.22.168.
- The enzyme from some sources also acts on L-cystine, forming
pyruvate, ammonia and cysteine persulfide, and a number of related
- Possibly identical, in Saccharomyces cerevisiae, with EC 22.214.171.124.
