The enzyme monoterpene ε-lactone hydrolase (EC 3.1.1.83, MLH; systematic name isoprop(en)ylmethyloxepan-2-one lactonohydrolase catalyses the reaction
(1) isoprop(en)ylmethyloxepan-2-one + H2O
⇌
{\displaystyle \rightleftharpoons }
6-hydroxyisoprop(en)ylmethylhexanoate (general reaction)
(2) 4-isopropenyl-7-methyloxepan-2-one + H2O
⇌
{\displaystyle \rightleftharpoons }
6-hydroxy-3-isopropenylheptanoate
(3) 7-isopropyl-4-methyloxepan-2-one + H2O
⇌
{\displaystyle \rightleftharpoons }
6-hydroxy-3,7-dimethyloctanoate
The enzyme catalyses the ring opening of ε-lactones in Gram-positive bacterium Rhodococcus erythropolis DCL14.
