Membranes of the adrenal medulla. Behaviour of insoluble proteins of chromaffin granules on gel electrophoresis.
Washed membranes of bovine adrenal chromaffin granules contained most of the cholesterol and phospholipids of the particle and 22% of the total protein. The protein/lipid ratio was about 0.45 (w/w). Dopamine(3,4-dihydroxyphenethylamine)beta-hydroxylase, Mg(2+)-activated nucleoside triphosphatase and cytochrome b-559 activities were present in the membrane. ATP was the best substrate for the nuc...
متن کاملThe Adenosine-triphosphatase Activity of Adrenal Chromaffin Granules.
1. The preparation of a fraction containing highly purified chromaffin granules from the bovine adrenal medulla is described. 2. The fraction contains an adenosine-triphosphatase activity that is stimulated by Mg(2+) and that cannot be explained by contamination with mitochondria or microsomes. 3. It is suggested that the adenosine-triphosphatase activity is related to the uptake of cate-cholam...

Calcium dynamics in bovine adrenal medulla chromaffin cell secretory granules.
The secretory granules constitute one of the less well-known compartments in terms of Ca2+ dynamics. They contain large amounts of total Ca2+, but the free intragranular [Ca2+] ([Ca2+]SG), the mechanisms for Ca2+ uptake and release from the granules and their physiological significance regarding exocytosis are still matters of debate. We used in the present work an aequorin chimera targeted to ...
