Acetylcholinesterase activity in vertebrate spermatozoa


, : Acetylcholinesterase activity in vertebrate spermatozoa. VII World Congress on Fertility and Sterility, 17-25 October, 1971, Tokyo/Kyoto Abstracts: 4

Spermatozoa from 5 species, including cattle and rats, were examined. Acetylcholinesterase activity was localised in the mid-piece of the spermatozoa. Activity was considerably reduced in stored bull spermatozoa. There was no indication of localisation of activity in the sperm head. However, in mechanically separated spermatozoa, activity is seen at the base of the head.

The influence of a cloned trpE (trpE+p) gene from Bacillus pumilus on the expression of the gat locus in Bacillus subtilis was examined. The trpE gene was regulated by tryptophan and the mtr locus, which specifies the presumed aporepressor. The sp...
