Protein conformations and their stability

Journal of the American Oil Chemists' Society, 1983
AbstractOur understanding of the conformations of proteins and their stability has increased substantially in recent years. A reaction of considerable interest is native (N) ⇌ denatured (D) where N is the globular, native state of the protein which is now well defined as a result of numer‐ous structural determinations by X‐ray diffraction studies, and ...

Structure and Conformational Stability of Protonated Dialanine

The Journal of Physical Chemistry A, 2010
A systematic investigation on the structure and stability of the four conformers of the protonated dialanine cation (transA1, transA2, transO1, cisA3) was performed employing the HF, MP2, and hybrid DFT methods with various basis sets which ranged from the 6-31G* to the basis set larger than the correlation consistent aug-cc-pVTZ basis set. It is found

Charge repulsion in the conformational stability of melittin

Biochemistry, 1992
Electrostatic repulsion between positively charged groups has been suggested to be critical in determining the conformation of melittin. To clarify the role of repulsive forces, we prepared a series of succinylated melittins, an acetylated melittin, and a synthetic melittin mutant, with various degrees of charge repulsion.

Sucrose modifies ribosomal stability and conformation

Biochimie, 1984
High concentrations of sucrose have a strong protective effect on heat-induced modifications of rat liver ribosomal subunits. They prevent to a large extent subunit inactivation, measured by poly (U)-dependent [14C] Phe tRNA binding (40S subunits) and puromycin reaction (60S subunits), subunit unfolding into light forms, and the release of both free ...

Conformational stability and vibrations of aminopropylsilanol molecule

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2006
Density functional theory (DFT), using the B3-LYP/6-31G(d,p) method have been used to investigate the conformation and vibrational spectra of aminopropylsilanetriol (APST) NH2CH2CH2CH2Si(OH)3. The potential function for CCCSi torsion gives rise to two distinct conformers trans and gauche.

Effect of Edta on the Conformational Stability of Thermolysin

1976
Thermolysin is a remarkably thermostable metallo endopeptidase produced by Bacillus Thermoproteolyticus Rokko[l]. The enzyme contains one catalytically essential zinc as well as four calcium atoms per molecule[2l. Calcium ions are not directly involved with the catalytic activity, but the nature of interactions in which they partecipate, as obtained by
