Adenosine diphosphate and adenosine monophosphate: enzymatic spectrophotometric determination

The Journal of Nutritional Biochemistry, 1990
Determination enzymatique et spectrophotometrique de l'adenosine diphosphate (ADP) et de l'adenosine monophosphate (AMP). Phosphorylation de l'ADP par une pyruvate kinase puis reduction du pyruvate en presence de NADH. Mesure de la consommation de NADH au spectrophotometre a 340 nm.

Adenosine 3′, 5′-monophosphate in mycobacteria

Life Sciences, 1977
Abstract Cyclic adenosine 3′,5′-monophosphate (cyclic AMP) is present in saprophytic fast growing as well as pathogenic and non-pathogenic slow growing mycobacteria. Apparently there does not seem to be any direct relationship between either intra- or extra-cellular cyclic AMP content with the growth rate of the bacteria.

Measurement of adenosine 3′,5′-monophosphate

Analytical Biochemistry, 1967
Abstract A double-isotope dilution and derivative analysis technique is described for the measurement of adenosine 3′,5′-monophosphate. Column and paper chromatography are used for the isolation of adenosine 3′,5′-monophosphate from tissues and urine.

Cyclic Adenosine Monophosphate: Function in Photoreceptors

Science, 1971
Inactivation of adenylate cyclase in outer segments of retinal photoreceptor cells is proportional to the bleaching of rhodopsin. Membranes of the outer segments also contain a particulate, light-insensitive phosphodiesterase of high specific activity. In electrophysiological experiments, application of cyclic adenosine monophosphate along

Effects of adenosine 5′-monophosphate and adenosine 3′,5′-cyclic monophosphate on l cells

Journal of Cell Science, 1975
ABSTRACT The adenine nucleotides, 5′-AMP and 3′5′-cyclic AMP block L cells in the S-phase of the cell cycle. The intracellular level of cyclic AMP is reduced after incubation of cells with 5′-AMP, and rates of uridine transport are increased after incubation with either 5′-AMP or cyclic AMP.

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 ...
