Studies on tyrosine hydroxylase from bovine adrenal medulla.
Approximately 90% of the total tyrosine hydroxylase activity of bovine adrenal medulla homogenates was localized in the particulate fraction of the homogenate. The particulate enzyme was solubilized by incubation with trypsin, and the solubilized enzyme was partially purified. This enzyme was found to behave like the tyrosine hydroxylase which had been purified from the supernatant fraction by ...
متن کاملAtrial natriuretic polypeptide in bovine adrenal medulla.
Two radioimmunoassays for alpha-human atrial natriuretic polypeptide (alpha-hANP) with different specificities were used to study the tissue level and the nature of alpha-hANP-like immunoreactivity in the bovine adrenal gland. A considerable amount of alpha-hANP-like immunoreactivity was detected in the adrenal medulla (90.8 +/- 21.1 and 90.0 +/- 23.1 ng/g with the two radioimmunoassays), while...

متن کاملCalcium 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 ...
متن کاملCopper-induced alteration of muscarinic binding in bovine adrenal medulla.
In microsomes of bovine adrenal medulla, there were two affinity binding sites for carbamylcholine with a high and a low affinity. Copper (1-10 microM) largely enhanced the affinity of carbamylcholine at the low affinity binding site, with a slight increase in the affinity at the high affinity binding site. On the other hand, copper slightly decreased the binding affinity of pirenzepine and atr...
