Reaction of DNA with K2PdCl4 at pH 2.0 followed by a piperidine workup produces specific cleavage at adenine (A) residues. Product analysis revealed the K2PdCl4 reaction involves selective depurination at adenine, affording an excision reaction analogous to the other chemical DNA sequencing reactions. Adenine residues methylated at the exocyclic amine (N6) react with lower efficiency than unmet...

INTRODUCTION Mast cells play an important role in allergic responses. METHODS We herein demonstrated the mechanisms of inhibitory effect of adenine on IgE/antigen-induced degranulation and TNF-α release in mast cells. RESULTS We found that these effects were dependent on the amino group of adenine because purine only weakly inhibited degranulation. Adenine also inhibited Ca2+ ionophore- and...

The interaction of phosphoenolypyruvate with isolated rat liver mitochondria has been further investigated. The uptake of P-enolpyruvate is accompanied by the stoichiometric release of intramitochondrial adenine nucleotides resulting in the inhibition of mitochondrial protein synthesis. Addition of specific inhibitors of either the adenine nucleotide carrier or the tricarboylic acid carrier blo...

An enhanced Raman scattering from a thin layer of adenine molecules deposited on graphene substrate was detected. The value of enhancement depends on the photon energy of the exciting light. The benzene ring in the structure of adenine molecule suggests π-stacking of adenine molecule on top of graphene. So, it is proposed that the enhancement in the adenine Raman signal is explained by the reso...

A series of mouse-human hybrids was prepared from mouse cells deficient in adenine phosphoribosyltransferase (EC 2.4.2.7) and normal human cells. The hybrids were made in medium containing adenine and alanosine, an antimetabolite known to inhibit de novo adenylic acid biosynthesis. The mouse cells, unable to utilize exogenous adenine, were killed in this medium, but the hybrids proliferated as ...

This work investigates quantum transport in symmetrical and asymmetrical borospherene-based molecular junctions with adenine. Adenine is one of the four nucleobases DNA was selected because its excellent properties. The density functional/non-equilibrium Green's function (DFT-NEGF) mathematical approach utilized, which further used to calculate parameters including I–V curve, transmission spect...

RNase P from Bacillus subtilis cleaves in vitro the adenine riboswitch upstream of pbuE, which codes for an adenine efflux pump. The guanine riboswitch, encoded upstream of xpt-pbuX operon, is not cleaved. The cleavage sites do not occur at any predicted structures that should be recognized by RNase P in the theoretical model of the adenine riboswitch. However, it is possible to draw alternativ...
