The enzyme juvenile hormone esterase catalyzes the hydrolysis of juvenile hormone
The enzyme juvenile hormone esterase (EC 3.1.1.59, systematic name methyl-(2E,6E,10R)-10,11-epoxy-3,7,11-trimethyltrideca-2,6-dienoate acylhydrolase, JH esterase) catalyzes the hydrolysis of juvenile hormone: Nomenclature and function This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is methyl-(2E,6E)-(10R,11S)-10,11-epoxy-3,7,11-trimethyltrideca-2,6-dienoate acylhydrolase. Other names in common use include JH esterase, juvenile hormone esterase, and juvenile hormone carboxyesterase. Juvenile hormone (JH) controls insect metamorphosis. High JH titers…
