Cyclic adenosine monophosphate in bacteria.

Science (New York, N.Y.), 1970
Both cyclic AMP and a specific inducer acting in concert are required for the synthesis of many inducible enzymes in E. coli. Little enzyme is made in the absence of either. In contrast to the specific inducers which stimulate the synthesis only of the proteins required for their metabolism, cyclic AMP controls the synthesis of many proteins.

Adenosine 3',5'-Monophosphate and Mania

JAMA: The Journal of the American Medical Association, 1971
Adenosine 3',5'-monophosphate (cyclic AMP) is currently of intense interest to scientists in many fields of biology and medicine. Cyclic AMP plays a central role in the mediation of hormonal actions and the regulation of metabolic processes. 1 There is considerable experimental evidence for an important role of cyclic AMP in brain function.

Electrochromatographic separation of inorganic phosphate, a adenosine monophosphate, adenosine diphosphate, and adenosine triphosphate

Analytical Biochemistry, 1963
Abstract Electrochromatography with carefully adjusted electrolyte solutions (0.003 M zinc acetate, 0.035 M citric acid, and 0.0148 M sodium citrate) at pH 3.8 is an effective technique for the separation of mixtures of phosphoric acid, adenosine monophosphate, adenosinc diphosphate, and adenosine triphosphate.

Stimulation of erythropoiesis by cyclic adenosine monophosphate

Life Sciences, 1971
Abstract CYCLIC AMP stimulated the incorporation of radioiron by the red blood cells in polycythemic mice. This effect was potentiated by prior incubation of cyclic AMP with dialyzed rat serum and was partially abolished in vivo , but not in vitro , by anti-erythropoietin.

Origin of Cyclic Adenosine Monophosphate in Saliva

Journal of Dental Research, 1975
The level of cyclic adenosine monophosphate (AMP) in duct saliva from the dog submandibular gland was increased after cyclic AMP was administered intravenously in vivo. Isoproterenol increased the level of cyclic AMP in plasma and saliva in vivo and in salivary gland slices in vitro, but increased the level only slightly in saliva in a perfused dog ...

Dibutyryl cyclic adenosine monophosphate inhibits pulmonary vasoconstriction

Lung, 1988
The effects of the cell-permeable dibutyryl derivative of cyclic AMP on the vascular reactivity of isolated perfused rat lungs were examined. In lungs perfused with homologous blood, pulmonary arterial infusion of db-cAMP (30 micrograms/min) inhibited hypoxia-induced vasoconstriction (IC50 = 6.3 X 10(-5) M) and vasoconstriction due to bolus injection ...

Heterogeneity of antibodies to adenosine 5′-monophosphate

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1976
Antibodies to adenosine 5'-monophosphate were produced in rabbits by injecting a conjugate of the nucleotide (oxidized with periodate) with bovine serum albumin. AMP-specific antibodies were isolated by affinity chromatography. The antiserum was first applied on oligoadenylic acids-agarose column and then the unbound proteins on a morpholine derivative

Adenosine-5-monophosphate catabolism in frog liver

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1987
1. AMP catabolism in frog liver extract was found to proceed exclusively through the formation of IMP. Further metabolism of IMP is relatively slow. 2. Among the enzymes involved in AMP catabolism, AMP deaminase is most active and adenosine deaminase and AMP 5'-nucleotidase exhibit only 20 and 10% of AMP deaminase activity respectively.

A chronocoulometric aptamer sensor for adenosine monophosphate

Chemical Communications, 2007
The selective recognition of adenosine monophosphate by a half-duplex aptamer-modified electrode leads to a simple chronocoulometric aptasensor based on the changes in surface charges.

Measurement of Plasma Adenosine 3',5'-Monophosphate*

The Journal of Clinical Endocrinology & Metabolism, 1978
Currently used methods for plasma cAMP measurements are either tedious (chromatographic preparation of sample) or potentially inaccurate (direct assay of plasma samples). A rapid, simple, and accurate competitive binding assay for plasma cAMP, which does not require chromatographic preparation of the sample, has been developed.
