Poly(adenosine diphosphate ribose)

1973
Publisher Summary This chapter discusses that incorporation of radioactivity of (adenine- 14 C) ATP into the acid insoluble material in a nuclear preparation from hen liver is enhanced at least 1000-fold by the presence of NMN. It is confirmed that this stimulation: using a nuclear preparation from rat liver.

Adenosine Diphosphate, Adenosine Triphosphate

1955
The increasing importance for animals and bacteria of adenosine diphosphate (ADP) and adenosine triphosphate (ATP) in energy-transfer mechanisms involving such widely diverse processes as muscular contraction, nerve conduction, fire fly luminescence, coenzyme syntheses, tumor growth, polysaccharide synthesis and many other key reactions (McElroy and ...

Magnesium, Adenosine Diphosphate and Blood Platelets

Nature, 1966
RECENTLY we reported1 a relative plasma magnesium deficiency in a group of forty male patients with acute myocardial infarction (mean of 2.3 mg per 100 ml.) compared with thirty-six normal healthy males (mean of 2.6 mg per 100 ml.) in the same age group. In addition it was shown that magnesium added to fresh whole blood delays the clumping of platelets

Nonenzymic adenosine 5'-diphosphate ribosylation of poly(adenosine diphosphate ribose).

Biochemistry, 1986
Poly(adenosine 5'-diphosphate ribose) [poly(ADP-ribose]) is spontaneously ADP-ribosylated when it is incubated with nicotinamide adenine dinucleotide, especially in 0.5 M NaCl and at an alkaline pH. The ADP-ribose residues are monomeric and are attached to the middle of polymer chains.

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 ...

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 ...

Adenosine Diphosphate Glucose and Glucoside Biosynthesis

Nature, 1962
URIDINE diphosphate glucose (UDPG) has been found to act as glucose donor in a number of enzymatic reactions, such as glucoside formation in plants1 and in locust2, sucrose and starch synthesis in plants3,4 and glycogen formation in mammals5.

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

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.
