ID 3.1.1.83 DE monoterpene epsilon-lactone hydrolase. AN MLH. CA (1) 4-isopropenyl-7-methyloxepan-2-one + H2O = 6-hydroxy-3- CA isopropenylheptanoate + H(+). CA (2) 7-isopropyl-4-methyloxepan-2-one + H2O = 6-hydroxy-3,7- CA dimethyloctanoate + H(+). CC -!- Catalyzes the ring opening of epsilon-lactones which are formed CC during degradation of dihydrocarveol by the Gram-positive bacterium CC Rhodococcus erythropolis DCL14. CC -!- Also acts on ethyl caproate, indicating that it is an esterase with a CC preference for lactones (internal cyclic esters). CC -!- Not stereoselective. DR Q9EX73, MLHB_RHOER ; //
