Direct evidence of the amino acid side chain and backbone contributions to protein anharmonicity.

J. Am. Chem. Soc. 132(4) , 1371-6, (2010)

Elastic incoherent neutron scattering has been used to study the temperature dependence of the mean-square displacements of nonexchangeable hydrogen atoms in powders of a series of homomeric polypeptides (polyglycine, polyalanine, polyphenylalanine and polyis...

Endoplasmic reticulum stress caused by aggregate-prone proteins containing homopolymeric amino acids.

FEBS J. 274(21) , 5619-27, (2007)

Many human proteins have homopolymeric amino acid (HPAA) tracts, but their physiological functions or cellular effects are not well understood. Previously, we expressed 20 HPAAs in mammalian cells and showed characteristic intracellular localization, in that ...

A solvent model for simulations of peptides in bilayers. I. Membrane-promoting alpha-helix formation.

Biophys. J. 76(5) , 2448-59, (1999)

We describe an efficient solvation model for proteins. In this model atomic solvation parameters imitating the hydrocarbon core of a membrane, water, and weak polar solvent (octanol) were developed. An optimal number of solvation parameters was chosen based o...

NEXAFS spectroscopy of homopolypeptides at all relevant absorption edges: polyisoleucine, polytyrosine, and polyhistidine.

J. Phys. Chem. B 111(33) , 9803-7, (2007)

Carefully calibrated high-resolution low-noise near-edge X-ray absorption fine structure spectra of three homopolypetides, viz., polyisoleucine, polytyrosine, and polyhistidine at the C, N, and O K-edges, are compared with the respective spectra of parent ami...

Molecular theory of the helix-coil transition in polyamino acids. V. Explanation of the different conformational behavior of valine, isoleucine, and leucine in aqueous solution.

Effect of streptomycin on the stoichiometry of GTP hydrolysis in a poly(U)-dependent cell-free translation system.

FEBS Lett. 192(1) , 165-9, (1985)

The technique of Sepharose-bound template translation has been used to estimate the stoichiometry of GTP hydrolysis during peptide elongation in the presence of streptomycin. The presence of streptomycin has been shown to have no great effect on the elongatio...

Vibrational dynamics of poly(L-isoleucine).

Int. J. Biol. Macromol. 46(2) , 131-9, (2010)

Normal mode analysis and their dispersion for poly(L-isoleucine) are reported by using Urey Bradley force field and Fourier transform IR. The calculated frequencies are found to be in reasonably good agreement with the Fourier transform IRspectra. Experimenta...
