Broken helix in vesicle and micelle-bound alpha-synuclein: Insights from site-directed spin labeling-EPR experiments and MD simulations

Autor: Marco Bortolus, Fabio Tombolato, Stefano Mammi, Isabella Tessari, Luigi Bubacco, Marco Bisaglia, Alberta Ferrarini, Anna Lisa Maniero

The region 35-43 of human alpha-Synuclein bound to small unilamellar lipid vesicles and to sodium dodecyl sulfate micelles has been investigated by site-directed spin labeling and electron paramagnetic resonance spectroscopy. The distance distributio

Dynamics of the nitroxide side-chain in spin labeled proteins

Autor: Jack H. Freed, Fabio Tombolato, Alberta Ferrarini

The dynamics of the tether linking methanethiosulfonate (MTSSL) spin probes to alpha-helices has been investigated with the purpose of rationalizing its effects on ESR line shapes. Torsional profiles for the chain bonds have been calculated ab initio

Modeling the effects of structure and dynamics of the nitroxide side chain on the ESR spectra of spin-labeled proteins

Autor: Jack H. Freed, Fabio Tombolato, Alberta Ferrarini

In the companion paper (J. Phys. Chem. B 2006, 110, jp0629487), a study of the conformational dynamics of methanethiosulfonate spin probes linked at a surface-exposed alpha-helix has been presented. Here, on the basis of this analysis, X-band ESR spe

Chiral Nematic Phase of Suspensions of Rodlike Viruses: Left-Handed Phase Helicity from a Right-Handed Molecular Helix

Autor: Eric Grelet, Alberta Ferrarini, Fabio Tombolato

Publikováno v: Physical Review Letters
Physical Review Letters, American Physical Society, 2006, 258302 (96), p. 258302(1-4). ⟨10.1103/PhysRevLett.96.258302⟩

4 pages; International audience; We report a study on charged, filamentous virus called M13, whose suspensions in water exhibit a chiral nematic (cholesteric) phase. In spite of the right-handed helicity of the virus, a left-handed phase helicity is

From the double-stranded helix to the chiral nematic phase of B-DNA: A molecular model

Autor: Fabio Tombolato, Alberta Ferrarini

Publikováno v: The Journal of Chemical Physics. 122:054908

B-DNA solutions of suitable concentration form left-handed chiral nematic phases (cholesterics). Such phases have also been observed in solutions of other stiff or semiflexible chiral polymers; magnitude and handedness of the cholesteric pitch are un
