Homology model of juvenile hormone esterase from the crop pest, Heliothis virescens.
Juvenile Hormone Esterase (JHE) plays an essential role in the development of insects since it is partially responsible for clearing juvenile hormone (JH), one of the hormones that is responsible for insect metamorphosis. JHE is a 60 kDa enzyme that selectively hydrolyzes the alpha/beta unsaturated ester of JH. Because of its pivotal role in insect development, we have targeted JHE for use as a...
متن کاملRole of juvenile hormone-esterase in mating-stimulated egg development in the moth Heliothis virescens.
Juvenile hormone (JH) titer in virgin females of Heliothis virescens is significantly lower than that in mated females of the same age. The JH titer in virgin females follows a diel pattern in which it begins to increase towards the end of photophase, remains high around the onset of scotophase, and declines during scotophase. The titer reaches its lowest levels at the onset of photophase, and ...
متن کاملIsolation of juvenile hormone esterase and its partial cDNA clone from the beetle, Tenebrio molitor.
Juvenile hormone esterase (JHE) plays an essential role in insect development. It is partially responsible for the clearance of juvenile hormone (JH) which regulates various aspects of insect development and reproduction. Because of its role in regulating JH titer, this enzyme has been targeted for development of biologically-based insecticides. JHE was partially purified from the beetle, Teneb...
متن کاملIsolation and characterization of full-length cDNA clones coding for cholinesterase from fetal human tissues.
To study the primary structure and regulation of human cholinesterases, oligodeoxynucleotide probes were prepared according to a consensus peptide sequence present in the active site of both human serum pseudocholinesterase (BtChoEase; EC 3.1.1.8) and Torpedo electric organ "true" acetylcholinesterase (AcChoEase; EC 3.1.1.7). Using these probes, we isolated several cDNA clones from lambda gt10 ...
