Binding of Adenosine Diphosphate to Turkey Thrombocytes

Haemostasis, 2009
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 with 125I.

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 ...

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.

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

Adenosine Diphosphate-Degrading Activity in Placenta

Clinical Science, 1983
1. The degradation of ADP by the placenta and umbilical artery was investigated. 2. Supernatants from incubations of finely chopped placental and umbilical arterial tissue were incubated with [14C]ADP for various durations from 0 to 30 min. 3.

Synthesis of Adenosine Diphosphate Ribose Histidine

Organic Letters
Adenosine diphosphate ribosylated histidine (His-ADPr) is a vital signaling molecule for the bacterial immune system, the antiphage system in particular. In this unique second messenger molecule, the distal nitrogen of the histidine side chain is ribosylated in a β fashion.

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.
