limonene = mentha-1,8-diene
limonene-1,2-epoxide = 1,2-epoxymenth-8-ene
limonene-1,2-diol = menth-8-ene-1,2-diol
Other name(s): limonene oxide hydrolase
Systematic name: limonene-1,2-epoxide hydrolase
Comment: Involved in the monoterpene degradation pathway of the actinomycete Rhodococcus erythropolis. Enzyme hydrolyses several alicyclic and 1-methyl-substituted epoxides, such as 1-methylcyclohexene oxide, indene oxide and cyclohexene oxide. It differs from the previously described epoxide hydrolases [EC 184.108.40.206 (trans-epoxysuccinate hydrolase), EC 220.127.116.11 (leukotriene-A4 hydrolase), EC 18.104.22.168 (hepoxilin-epoxide hydrolase), EC 22.214.171.124 (microsomal epoxide hydrolase) and EC 126.96.36.199 (soluble epoxide hydrolase)] as it is not inhibited by 2-bromo-4'-nitroacetophenone, diethyl dicarbonate, 4-fluorochalcone oxide or 1,10-phenanthroline.
