Abstract A new, dynamic cycling procedure for total adenine nucleotides (ATP + ADP + AMP) is described. This procedure permits the measurement of adenine nucleotides in TCA extracts of fresh or frozen blood samples without requiring the removal of TCA from extract.

On the mutagenic action of adenine
Leukemia Research, 2007The deamination of cytosine and adenine is mutagenic; the deamination of guanine is not. The deamination of cytosine leads to G=C-->A=T point mutation and to G-->A and C-->T transition in the DNA molecule; the deamination of adenine leads to the opposite A-->G and T-->C transition.

On the interaction of hypoxanthine with adenine
Experientia, 1967Une conversion non-enzymatique d'hypoxanthine en adenine fut proposee sur la base d'observations spectrophotometriques obtenues de solutions contenant adenine et hypoxanthine dans 1–5M de phosphate d'ammonium. Les resultats fournis par les experiences sur la radioactivite ne confirme pas la conclusion emise parBowne2 que hypoxanthine et adenine ...

The Radiation Decomposition of Adenine
Radiation Research, 1963The radiolysis of 0.1% solutions of adenine in water leads to the formation of two major products: 4,6-diamino-5formamidopyrimidine and 8- hydroxyadenine. The two compounds account for about 80% of the decomposed adenine. Minor products are hypoxanthine and 4-amino-5formamido-6- hydroxypyrimidine.

Equilibrium adsorption isotherm data for the purine base adenine has been obtained on several prebiotically relevant minerals by frontal analysis using water as a mobile phase. Adenine is far displaced toward adsorption on pyrite (FeS2), quartz (SiO2), and pyrrhotite (FeS), but somewhat less for magnetite (Fe3O4) and forsterite (Mg2SiO4). The prebiotic

Publisher Summary This chapter discusses the determination of flavine adenine dinucleotide (FAD) that depends on the specific reactivation of the apoenzyme of D-amino acid oxidase from pig kidney by this coenzyme. Comparison of the reactivation with a standard solution of FAD is necessary because the Michaelis constant of the enzyme for F AD varies ...
