Microscopic origins of entropy, heat capacity and the glass transition in proteins

Article Abstract:

Research is presented regarding the internal motions of protein macromolecules, and the microscopic origins of heat capacity, entropy, and glass transition in proteins. Measurements were made of how dependent the fast dynamics of methyl-carrying side chains in a calmodulin-peptide complex are on temperature, using deuterium NMR relaxation methods.

Conformational entropy in molecular recognition by proteins

Article Abstract:

Molecular recognition by proteins is a very important phenomenon for every biological process, especially the protein associations underlying cellular signal transduction. The changes in protein conformational entropy are found to be of great significance to the free energy of the protein-ligand association.

A larger pool of ozone-forming carbon compounds in urban atmosphere

Article Abstract:

Studies show that urban ozone production in Europe is governed by the availability of volatile organic compounds (VOCs), but analysis of the VOCs lacks resolution. A new study describes an improved method of isolating and classifying over 500 types of VOCs.
