Description:
A nonspecific carboxylesterase (esterase 6) of Drosophila melanogaster shows greater activity in adult males than in females and is highly concentrated in the anterior ejaculatory duct of the reproductive tract of the male. Esterase 6 is depleted in males by copulation and is transferred to females early during copulation as a component of the seminal fluid. That esterase 6 may be involved in a system controlling the timing of remating is suggested by differences in the activity of this enzyme in a strain of Drosophila selected for a decrease in time to remating and by differences in the timing of remating in females initially inseminated by males lacking or having active esterase 6.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Richmond, R C -- Gilbert, D G -- Sheehan, K B -- Gromko, M H -- Butterworth, F M -- New York, N.Y. -- Science. 1980 Mar 28;207(4438):1483-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6767273" target="_blank"〉PubMed〈/a〉
