title: Angiotensin II stimulation of 5'-adenylic acid deaminase.
abstract: Angiotensin II has been found to stimulate 5'-adenylic acid deaminase from rabbit skeletal muscle. Stimulation was discernible around 10(-9) M and peak stimulation of about threefold was seen at 10(-7) M, concentrations approximating those required for stimulation of vascular smooth muscle or adrenal glomerulosa cells. Higher concentrations produced less stimulation. Adenosine triphosphate stimulated to the same degree, but a concentration of 10(-5) M was required for maximum stimulation, while maximum stimulation with sodium or potassium required 0.5 M and 0.75 M, respectively. Although the physiologic significance of these observations has not been established, these data suggest an intracellular role for angiotensin II.
