Differential binding of cyclic adenosine 3' ,5'-monophosphate to the cyclic adenosine 3' ,5'-monophosphate receptor protein in Escherichia coli.

Binding of cyclic adenosine 3' ,5'-monophosphate (cAMP) by the cAMP receptor protein in crude cell-free extracts of Escherichia coli was characterized. When cell were grown in glucose, binding was inhibited 50% relative to extracts from cells grown with succinate as carbon source . This inhibition could be relieved by dialysis.

Renal Effects of Adenosine 3 ' , 5 ' - Cyclic Monophosphate and Dibutyryl Adenosine 3 , 5 ' - Cyclic Monophosphate

An abstract of this work appeared in 1970 Abstracts, The American Society of Nephrology. Received for publication 27 October 1970 and in revised form 28 January 1971. similar to the effect of renal arterial infusion of isoproterenol. The results suggest that synthesis of cyclic AMP in proximal renal tubule cells in response to stimulation of beta adrenergic or other receptors can mediate a decr...

3',5'-cyclic adenosine monophosphate-requiring mutants of Escherichia coli.

Mutants that require exogenous 3',5'-cyclic adenosine monophosphate (cAMP) for exponential growth were isolated from strains deficient in adenyl cyclase. Studies of one strain showed that cAMP is not incorporated into macromolecules; instead, it seems to have a regulatory function, i.e., in media lacking cAMP, cells form ribonucleic acid (RNA) and protein at linear rather than exponential rates...

A protein binding assay for adenosine 3':5'-cyclic monophosphate.

A simple and sensitive assay for adenosine 3':5'-cyclic monophosphate (cAMP) has been developed that is based on competition for protein binding of the nucleotide, presumably to a cAMP-dependent protein kinase. The nucleotide-protein complex is adsorbed on a cellulose ester filter. Assay conditions are such that a binding constant approaching 10(-9) M is obtained, and the assay is thus sensitiv...
