The amount and compartmentalization of adenosine diphosphate in muscle

Biochimica et Biophysica Acta, 1962
Abstract A fraction of the ADP in muscle was extracted with aqueous ethanol at low temperature, and if the extractanta contained citrate there was no loss of ADP during or after the extraction. The quantity so determined in this work averaged about 0.25 μmole/g; there was some indication, but no explicit proof, that this figure should be corrected ...

A 5′-amino analog of adenosine diphosphate

Biochemical and Biophysical Research Communications, 1973
Abstract The synthesis and properties of the 5′-amino analog of adenosine diphosphate are described. The 5′-amino-5′-deoxyadenosine 5′-N-diphosphate (NADP) is prepared from the previously described aminonucleoside triphosphate by the hexokinase catalyzed transfer of the terminal phosphoryl to glucose. The NADP is stable in neutral or basic media, and

Studies on poly(adenosine diphosphate-ribose)

Archives of Biochemistry and Biophysics, 1971
Abstract Hydroxylapatite column chromatography was used for purification of poly (ADP-Rib). With an increasing concentration gradient of phosphate buffer (pH 6.8) RNA, DNA, and poly (ADP-Rib) with a chain of 17–18 ADP-ribose units were eluted successively.

Binding of Adenosine Diphosphate to Turkey Thrombocytes

Pathophysiology of Haemostasis and Thrombosis, 1982
Adenosine diphosphate (ADP) caused rapid and reversible aggregation of turkey thrombocytes, as determined by optical and microscopical examination. To investigate the binding of ADP to these cells, turkey thrombocyte-rich plasma was incubated with ADP-8–¹⁴C or ADP-3–³H and with human serum albumin labeled ...

On the inhibition of myosin-ATPase by adenosine diphosphate

Archives of Biochemistry and Biophysics, 1962
Abstract The myosin ATP-ase us inhibited by ADP competitively. The inhibitation constant is 33 times the Michaelis constant. This small amount of inhibition explains the product versus time curve of the ATP hydrolysis and is confirmed by this curve. The association constant of CaAdp was determined as 1050.

Bound adenosine diphosphate and adenosine triphosphate in resting and contracting muscle

Archives of Biochemistry and Biophysics, 1966
Abstract Resting muscle contains bound ADP in sufficient quantity to indicate that all the actin is present in the fibrous form, and that the binding in vivo is present to the same extent as has been found with the isolated protein. There is sufficient bound ATP to support the hypothesis of multiple binding sites to myosin.

Changes in poly(adenosine diphosphate-ribose) and poly(adenosine diphosphate-ribose) polymerase in synchronous HeLa cells

Biochemistry, 1976
An antibody has been prepared which is highly specific for poly(adenosine diphosphate-ribose). Neither poly(A), DNA, nor a variety of adenine-containing nucleosides or nucleotides were effective in competing with poly(ADP-ribose) for binding to the antibody. Of all compounds tested, only adenosine diphosphate-ribose competed for binding to the antibody.

Action of adenosine diphosphate on human platelets

Experientia, 1968
Es wird gezeigt, dass der ATP-Gehalt der Thrombocyten in blutplattchenreichem Plasma mit ADP inkubiert abfallt, wahrend deren 5-HT-Gehalt unverandert bleibt. Thrombocyten, die nach 5-HT-Sattigung inkubiert werden, verlieren sowohl ATP wie auch 5-HT.
