Major Contribution of the Basic Amino Acid Lysine at Position 11 to the Bioactivity of ACTH in Purified Isolated Rat Adrenocortical Cells

Autor: Henny J.M. Goverde, G.J. Pesman, A.G.H. Smals

Publikováno v: Biochemical and Biophysical Research Communications. 190:1060-1065

The contribution of the positive charge of lysine in position 11 of ACTH to the corticosteroidogenicity was tested in a purified isolated rat adrenal cell assay. ACTH analogues with Lys11 or Arg11 had the same bioactivity. Replacement of lysine by no

Publikováno v: Life Sciences. 52:959-964

The relationship between bioactive and immunoreactive adrenocorticotrophin (ACTH) was studied under various conditions. Rats were stressed by ether and the immunoreactive (I-ACTH) and bioactive (B-ACTH) ACTH levels were compared to the normal values

The neuropeptide oxytocin (OT) has been detected in testis and epididymis of several mammals. The peptide affects steroidogenesis and sperm transport in vivo. Effects of OT on sperm motility in vitro seems to be contradictory. As no data are availabl
