Accepted name: phenyl-N-(sulfonatooxy)methanimidothioate sulfolyase
Reaction: phenyl-N-(sulfonatooxy)methanimidothioate = benzylthiocyanate + sulfate

Glossary: glucotropaeolin = 1-S-[(1Z)-2-phenyl-N-(sulfonatooxy)ethanimidoyl]-1-thio-β-D-glucopyranose
Other name(s): TFP (gene name) (ambiguous); thiocyanate-forming protein (ambiguous)
Systematic name: phenyl-N-(sulfonatooxy)methanimidothioate sulfate-lyase (benzylthiocyanate-forming)
Comments: The enzyme, characterized from the plant Lepidium sativum, is involved in the breakdown of the glucosinolate glucotropaeolin. Depending on the substrate, it can also form simple nitrile- and epithionitrile-containing products. cf. EC, thiohydroximate-O-sulfate sulfate/sulfur-lyase (nitrile-forming), and EC, N-(sulfonatooxy)alkenimidothioic acid sulfate-lyase (epithionitrile-forming).
