ENZYME entry: EC 5.3.99.12

Accepted Name
lachrymatory-factor synthase
Alternative Name(s)
LFS
Reaction catalysed
(E)-alk-1-en-1-SO-peroxol <=> (Z)-alkanethial oxide
Comment(s)
  • The enzyme is responsible for production of the irritating lachrymatory factor that is released by onions and related species when they are chopped.
  • It acts on the product of EC 4.4.1.4.
  • The enzyme from Allium cepa (onion) acts on (E)-prop-1-en-1- SO-peroxol and produces (Z)-propanethial oxide, while the enzyme from Allium siculum (honey garlic) acts on (E)-but-1-en-1-SO-peroxol and produces (Z)-butanethial oxide.
