Description:
A protein that may be an enkephalin precursor has been identified in extracts of bovine adrenal medulla. This protein (about 50,000 daltons) appears to contain seven copies of [Met]enkephalin and one copy of [Leu]enkephalin. Digestion with trypsin and carboxypeptidase B yields [Met]enkephalin and [Leu]enkephalin in a ratio of almost 7 to 1. The enkephalins were identified by chromatography and by their binding to opiate receptors. Some characteristics of several other adrenal peptides that may serve as intermediates in the biosynthesis of the enkephalins are presented.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lewis, R V -- Stern, A S -- Kimura, S -- Rossier, J -- Stein, S -- Udenfriend, S -- New York, N.Y. -- Science. 1980 Jun 27;208(4451):1459-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7384787" target="_blank"〉PubMed〈/a〉
