Sysname
N-(sulfonatooxy)prop-2-enimidothioate sulfate-lyase (prop2-enylthiocyanate-forming)
Reaction(IUBMB)
(1) N-(sulfonatooxy)prop-2-enimidothioate = prop-2-enylthiocyanate + sulfate [RN:R13133];
(2) N-(sulfonatooxy)prop-2-enimidothioate = 2-(thiiran-2-yl)acetonitrile + sulfate [RN:R13134]
Reaction(KEGG)
R13133 R13134
Substrate
N-(sulfonatooxy)prop-2-enimidothioate [CPD:C22641]
Product
prop-2-enylthiocyanate [CPD:C22642];
sulfate [CPD:C00059];
2-(thiiran-2-yl)acetonitrile [CPD:C22643]
Comment
The enzyme, characterized from the plant Thlaspi arvense, is involved in the breakdown of the glucosinolate sinigrin. Depending on the substrate, it can also form simple nitrile-containing products. cf. EC 4.8.1.5, thiohydroximate-O-sulfate sulfate/sulfur-lyase (nitrile-forming) and EC 4.8.1.6, N-(sulfonatooxy)alkenimidothioic acid sulfate-lyase (epithionitrile-forming).
