S-alkylcysteine lyase

In enzymology, a S-alkylcysteine lyase is an enzyme that catalyzes the chemical reaction


 * an S-alkyl-L-cysteine + H2O $$\rightleftharpoons$$ an alkyl thiol + NH3 + pyruvate

Thus, the two substrates of this enzyme are S-alkyl-L-cysteine and H2O, whereas its 3 products are alkyl thiol, NH3, and pyruvate.

This enzyme belongs to the family of lyases, specifically the class of carbon-sulfur lyases. The systematic name of this enzyme class is S-alkyl-L-cysteine alkyl-thiol-lyase (deaminating; pyruvate-forming). Other names in common use include S-alkylcysteinase, alkylcysteine lyase, S-alkyl-L-cysteine sulfoxide lyase, S-alkyl-L-cysteine lyase, S-alkyl-L-cysteinase, alkyl cysteine lyase, and S-alkyl-L-cysteine alkylthiol-lyase (deaminating). It employs one cofactor, pyridoxal phosphate.
