EC 3.1.1.59     
Accepted name: juvenile-hormone esterase
Reaction: (1) juvenile hormone I + H2O = juvenile hormone I acid + methanol
(2) juvenile hormone III + H2O = juvenile hormone III acid + methanol

Glossary: juvenile hormone I = methyl (2E,6E,10R,11S)-10,11-epoxy-7-ethyl-3,11-dimethyl-2,6-tridecadienoate
juvenile hormone I acid = (2E,6E,10R,11S)-10,11-epoxy-7-ethyl-3,11-dimethyl-2,6-tridecadienoate
juvenile hormone III = methyl (2E,6E,10R)-10,11-epoxy-3,7,11-trimethyldodeca-2,6-dienoate
juvenile hormone III acid = (2E,6E,10R)-10,11-epoxy-3,7,11-trimethyldodeca-2,6-dienoate
Other name(s): JH-esterase; juvenile hormone analog esterase; juvenile hormone carboxyesterase; methyl-(2E,6E)-(10R,11S)-10,11-epoxy-3,7,11-trimethyltrideca-2,6-dienoate acylhydrolase
Systematic name: methyl-(2E,6E,10R)-10,11-epoxy-3,7,11-trimethyltrideca-2,6-dienoate acylhydrolase
Comments: Demethylates the insect juvenile hormones JH1 and JH3, but does not hydrolyse the analogous ethyl or isopropyl esters.
