Purification of the regulatory component of adenylate cyclase.
The regulatory component (G/F) of adenylate cyclase [ATP pyrophosphate-lyase (cyclizing), EC 4.6.1.1] from rabbit liver plasma membranes has been purified essentially to homogeneity. The purification was accomplished by three chromatographic procedures in sodium cholate-containing solutions, followed by three steps in Lubrol-containing solutions. The specific activity of G/F was enriched 2000-f...
متن کاملPurification and properties of the inhibitory guanine nucleotide-binding regulatory component of adenylate cyclase.
Attenuation of GTP-dependent inhibition of adenylate cyclase by islet-activating protein (pertussis toxin) is due to the ability of the toxin to catalyze the ADP-ribosylation of a 41,000/35,000-Da membrane-bound protein, which is thought to be the inhibitory guanine nucleotide-binding regulatory component of adenylate cyclase (Gi). We describe and document the purification of this protein from ...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولNovel regulatory properties of human type 9 adenylate cyclase.
Nine membrane-bound members of the mammalian adenylate cyclase family have been identified. The least characterized and most divergent in sequence of the nine adenylate cyclase isoforms is AC9. Stimulation by Galpha(s) and inhibition by Ca2+/calcineurin are two modes of regulation that have been reported for AC9. We explored the possibility of additional modes of regulation of human AC9. We now...
متن کاملThe subunits of the stimulatory regulatory component of adenylate cyclase. Resolution, activity, and properties of the 35,000-dalton (beta) subunit.
The stimulatory guanine nucleotide-binding regulatory component (G/F) of adenylate cyclase is activated by exposure to guanine nucleotide analogs or to Al3+ + F-. Activated G/F can reconstitute adenylate cyclase activity when mixed with the catalytic moiety of the enzyme system in the absence of an effective free concentration of stimulatory ligand. Activation is explained by dissociation of th...
