Amyloid-like self-assembly of a dodecapeptide sequence from the adenovirus fiber shaft: Perspectives from molecular dynamics simulations
(2011)Peptide and protein self-assembly is related to the fundamental problems of protein folding and misfolding and has potential applications in medicine, materials science and nanotechnology. Sequence repeats from self-assembling ...

Conformational analysis of compstatin analogues with molecular dynamics simulations in explicit water
(2007)The cyclic 13-residue peptide compstatin is a potential therapeutic agent against the unregulated activation of the complement system. A thorough knowledge of its structural and dynamical properties in solution may assist ...

Dynamic responses in polymer-clay gels
(2005)The shear orientation of three polymer-clay gels has been investigated by means of small angle neutron scattering (SANS). The gels have the same polymer and clay concentrations but different polymer molecular weight. The ...

Effects of hofmeister anions on DPPC langmuir monolayers at the air-water interface
(2004)In this work we investigated the effect of sodium salts of different monovalent anions belonging to the Hofmeister series on Langmuir monolayers of DPPC (1,2-dipalmitoyl phosphatidylcholine). The salts used were NaCl, NaBr, ...

Electron transfer contact maps
(1997)An exact approach is introduced to establish and compare quantitative structure-function relationships in electron transfer proteins. The strategy is based on the idea of an electron transfer contact map and is motivated ...

Evidence for the presence of two conformations of the heme a 3-CuB pocket of cytochrome caa 3 from Thermus thermophilus
(2011)Resonance Raman (RR) and "light" minus "dark" Fourier transform infrared (FTIR) difference spectra are reported for the CO-bound caa3 oxidase from Thermus thermophilus. Two Fe-CO stretching modes at 518 and 507 cm-1, the ...

Hula-twist photoisomerization of a styrene derivative examined by argon-matrix-infrared-spectroscopic method
(2006)IR spectra of α-cyano- o -fluorocinnamonitrile, its vinyl deuterated analogue and the corresponding photoproducts were recorded under Ar matrix isolation conditions (13K). An analysis of the IR spectra, assisted by ...

Article
Large scale structures in nanocomposite hydrogels
(2005)The physical picture of the large scale structures in nanocomposite hydrogels and some of their unique behavior were discussed. The aqueous solutions of the synthetic hectorite type clay, Laponite RD (LRD) and poly(ethylene ...

Nitric-oxide reductase: Structure and properties of the catalytic site from resonance Raman scattering
(2002)We have applied resonance Raman spectroscopy to investigate the properties of the dinuclear center of oxidized, reduced, and NO-bound nitric-oxide reductase from Paracoccus denitrificans. The spectra of the oxidized enzyme ...

Simultaneous resonance Raman detection of the heme a3-Fe-CO and CuB-CO species in CO-bound ba3-cytochrome c oxidase from Thermus thermophilus: Evidence for a charge transfer CuB-CO transition
(2004)Understanding of the chemical nature of the dioxygen and nitric oxide moiety of ba3-cytochrome c oxidase from Thermus thermophilus is crucial for elucidation of its physiological function. In the present work, direct ...
