HPLC analysis of cyclic adenosine diphosphate ribose and adenosine diphosphate ribose: determination of NAD+ metabolites in hippocampal membranes.

The Italian journal of biochemistry, 1995
Cyclic adenosine diphosphate-ribose (cADPR) and ADPR were separated by high-performance liquid chromatography (HPLC) on a CarboPac PA-1 column at strong basic pH and quantitated by a pulsed amperometric detector. Although this HPLC method was quite sensitive and highly reproducible, it did not allow the separation of cADPR from guanosine monophosphate (

Cyclic aristeromycin diphosphate ribose: A potent and poorly hydrolysable Ca2+-mobilising mimic of cyclic adenosine diphosphate ribose [PDF]

FEBS Letters, 1996
Cyclic aristeromycin diphosphate ribose, a carbocyclic analogue of cyclic adenosine diphosphate ribose, was synthesised using a chemo-enzymatic route involving activation of aristeromycin 5′-phosphate by diphenyl phosphochloridate.

Inositol trisphosphate and cyclic adenosine diphosphate-ribose increase quantal transmitter release at frog motor nerve terminals: possible involvement of smooth endoplasmic reticulum

Neuroscience, 1999
The release of chemical transmitter from nerve terminals is critically dependent on a transient increase in intracellular Ca2+.6,25 The increase in Ca2+ may be due to influx of Ca2+ from the extracellular fluid15 or release of Ca2+ from intracellular ...

ADENOSINE DIPHOSPHATE RIBOSE PYROPHOSPHOHYDROLASE IN HUMAN SKIN

The Journal of Dermatology, 1980
ABSTRACTAdenosine diphosphate ribose (ADPR) pyrophosphohydrolase (ADPR‐PPase), which catalyzes the hydrolysis of ADPR to yield adenosine monophosphate (AMP) and ribose‐5′‐phosphate, was assayed in human penile foreskin. Since ADPR is formed from nicotinamide adenine dinucleotide (NAD) by NAD glycohydrolase (NADase), NADase was also assayed in human ...

Presence and turnover of adenosine diphosphate ribose in human erythrocytes

Biochemical and Biophysical Research Communications, 1992
ADP-ribose was detected in human red blood cells (RBC) at 0.45 +/- 0.1 microM concentrations. These levels could be estimated after purification of ADP-ribose by means of three sequential HPLC fractionations of RBC extracts. Extraction was performed by sonication of RBC either in trichloroacetic acid, followed by centrifugation, or in carbonate ...

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.

Noncovalent interactions of poly(adenosine diphosphate ribose) with histones

Biochemistry, 1992
Covalent linkage of ADP-ribose polymers to proteins is generally considered essential for the posttranslational modification of protein function by poly(ADP-ribosyl)ation. Here we demonstrate an alternative way by which ADP-ribose polymers may modify protein function.

Studies on anti-poly(adenosine diphosphate ribose) antibody

Biochemical and Biophysical Research Communications, 1974
Summary Specific antibody against poly(ADP-Rib) was produced in a rabbit by injecting poly(ADP-Rib) mixed with methylated bovine serum albumin. Under standardized conditions, 1 mg of purified anti-poly(ADP-Rib) antibody combined with 400 pmoles (4 μg) of poly(ADP-Rib) and was retained on a millipore filter.
