The aim of this present work was the study of the intermolecular complexes between amphotericin B (AmB) and either cholesterol or ergosterol. In such complexes the intermolecular interaction energy… (More)

We showed recently that the high-salt transition of poly[d(G-C)]. poly[d(G-C)] between B-DNA and Z-DNA (at [NaCl] = 2.25 M or [MgCl(2)] = 0.7 M) can be ascribed to the lesser electrostatic free… (More)
This report derives an algebraic expression in closed form for the Poisson-Boltzmann free energy of weakly charged polyelectrolyte cylinders.

Uteroglobin (UTG) forms a fascinating homodimeric structure that binds small- to medium-sized ligands through an internal hydrophobic cavity, located at the interface between the two monomers.… (More)

The effect of interaction with DNA and oligonucleotides on the photophysical properties of two thiazole orange (TO) derivatives, with different side chains (-(CH2)3-N+(CH3)3 and -(CH2)6-I)) linked to… (More)

Whereas the phosphates of B-DNA jut out into the solution, those of Z-DNA, being closer to DNA matter, are less subject to electrostatic screening by counterions. We present simple planar models of… (More)

Results of molecular mechanics and dynamics calculations on intercalation complexes of DNA with various furocoumarins (psoralen, angelicin, 7-methylpyrido[3,4-c]psoralen and… (More)

We develop and test a Poisson-Boltzmann model of the electrostatics of the B-Z transition of DNA. Starting from the detailed geometries of the two forms, we compute at each radius the fractions of… (More)

When it is gel filtered on Sephadex in the absence of calcium ions, basic phospholipase A2 from Naja nigricollis venom elutes as a dimer. In order to study the possibility of this dimerization from a… (More)

We have previously shown that the anticodon of methionine tRNAs contains the major recognition site required for aminoacylation of tRNAs by Escherichia coli methionyl-tRNA synthetase (MetRS) and have… (More)
