Structural highlights
Function
HYEP_BOMMO Catalyzes juvenile hormone hydrolysis. Degrades juvenile hormone III (JH III) about 3 times and 5 times slower than juvenile hormone I (JH I) and II (JH II), respectively. Degrades cis-stilbene oxide and trans-stilbene oxide about 18 and 43 times slower than JH III, respectively.[1]
Publication Abstract from PubMed
The juvenile hormone (JH) epoxide hydrolase (JHEH) catalyzes the degradation of JH, which regulates the metamorphosis development of insects. Here we report the 2.30 A crystal structure of JHEH from the silkworm Bombyx mori (BmJHEH). The overall structure of BmJHEH is composed of an N-terminal segment followed by a core hydrolase domain, which is interrupted by an all-alpha lid domain. Structural analyses together with molecular simulation reveal insights into the conservation and specificity of the active-site pocket. These findings increase our understanding of the substrate recognition and catalysis of microsomal epoxide hydrolase family and might help the design of JH-derived pesticides. (c) Proteins 2014;.
