| abstract | - In enzymology, an alliin lyase (EC 4.4.1.4) is an enzyme that catalyzes the chemical reaction 蒜胺酸酶是洋蔥令人流淚的原因。只要切洋蔥時不要把根切開就可以了。甄文達。 an S-alkyl-L-cysteine S-oxide an alkyl sulfenate + 2-aminoacrylate Hence, this enzyme has one substrate, S-alkyl-L-cysteine S-oxide, and two products, alkyl sulfenate and 2-aminoacrylate. 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 S-oxide alkyl-sulfenate-lyase (2-aminoacrylate-forming). Other names in common use include alliinase, cysteine sulfoxide lyase, alkylcysteine sulfoxide lyase, S-alkylcysteine sulfoxide lyase, L-cysteine sulfoxide lyase, S-alkyl-L-cysteine sulfoxide lyase, and alliin alkyl-sulfenate-lyase. It employs one cofactor, pyridoxal phosphate. Many alliinases contain a novel N-terminal epidermal growth factor-like domain (EGF-like domain).
