TLDR
It was shown that, for the former three amino acids, known to have a positive surface tension increment, their perturbation of the surface free energy of water is consistent with their preferential exclusion from the protein surface.

Physiological and genetic responses of bacteria to osmotic stress.

TL;DR: This review is an account of the processes that mediate adaptation of bacteria to changes in their osmotic environment.
Journal ArticleDOI

The Hofmeister effect and the behaviour of water at interfaces.

TL;DR: The first general, detailed qualitative molecular mechanism for the origins of ion-specific (Hofmeister) effects on the surface potential difference at an air-water interface is proposed; this mechanism suggests a simple model for the behaviour of water at all interfaces, regardless of whether the non-aqueous component is neutral or charged, polar or non-polar.

Metabolic implications of stress-induced proline accumulation in plants

TL;DR: A mechanism is proposed whereby the interconversions of proline and P5C in different cell types and the associated transfer of redox potential between tissues may constitute a form of metabolic signalling within higher plants.
Journal ArticleDOI

The stabilization of proteins by osmolytes.

TL;DR: It was shown that all these substances stabilize the protein structure against thermal denaturation and (except for trimethylamine N-oxide for which interaction measurements could not be made) are strongly excluded from the protein domain, rendering unlikely their direct binding to proteins.
Journal ArticleDOI

The role of glycine betaine in the protection of plants from stress: clues from transgenic plants

TL;DR: Recent progress in the genetic manipulation of the synthesis of GB is summarized, with special emphasis on the relationship between the protective effects of GB in vivo and those documented in vitro.

Mechanism of protein stabilization by glycerol: preferential hydration in glycerol-water mixtures

Kunihiko Gekko, +1 more
- 04 Aug 1981 - 
TL;DR: A densimetric investigation of the interactions between solvent components in glycerol-water mixtures and seven proteins and all the proteins were found to be preferentially hydrated at all conditions used, i.e., addition of the proteins to the mixed solvent results in an increase in the chemical potential of Glycerol.
Journal ArticleDOI

The stabilization of proteins by sucrose.

TL;DR: The results from theprotein-solvent interaction study indicate that sucrose is preferentially excluded from the protein domain, increasing the free energy of the system and leading to protein stabilization.

Hydration of Proteins and Polypeptides

TL;DR: The chapter presents several proposals for predicting protein hydration based on the amino acid composition of the protein; however, the two main questions concerned include—whether ionic groups are more hydrated than other polar groups, and whether the amide and peptide functions are hydrated or not.
Journal ArticleDOI

Stabilization of protein structure by sugars.

TL;DR: The surface free energy perturbation by sugars plays a predominant role in their preferential interaction with proteins, and this effect was shown to increase with an increase in protein surface area, explaining the protein stabilizing action of these sugars and their enhancing effect of protein associations.
Journal ArticleDOI

Preferential interactions of proteins with salts in concentrated solutions

TL;DR: It was concluded that this does not necessarily lead to protein preferential hydration and stabilization in NaCl, NaCH3COO, and Na2SO4, since these salts have high surface tension increments.
