Hydrophobic moieties in cations, anions, and alcohols promote the B-to-Z transition in poly[d(G-C)] and poly[d(G-m5C)].

Abstract：

:Previous results from our laboratory showed that an increase in the nonpolar alkyl chain length in tetraalkylammonium cations is accompanied by greater efficiency in driving the B-to-Z transition. Analogous effects are observed when the hydrocarbon portion of carboxylate anions and alcohols is increased in size. The more hydrophobic species have a greater ordering effect on the aqueous solvent and promote formation of the less hydrated Z-DNA conformer.

  • Effect of D2O on maize plasmalemma ATPase and electron transport coupled proton pumping.

    abstract：:Heavy water (D2O) has been used as a putative inhibitor of the plasma membrane H(+)-ATPase and the plasma membrane redox system. Concentrations above 50% D2O inhibited H+ secretion and the plasma membrane redox system of Zea mays L. roots. Inhibition of H+ secretion by vanadate was reduced in presence of D2O. The plas...
