Global Conformational Dynamics in Ras [PDF]
Biochemistry, 2008 Ras and its homologues are central to regulation of a multitude of cellular processes. Ras in complex with GTP binds and activates its downstream signaling partners. (31)P NMR studies indicated that the Ras-GTP conformation is heterogeneous on a millisecond time scale, but details of its conformational dynamics remain unknown.

Protein Allostery and Conformational Dynamics [PDF]
Chemical Reviews, 2016 The functions of many proteins are regulated through allostery, whereby effector binding at a distal site changes the functional activity (e.g., substrate binding affinity or catalytic efficiency) at the active site. Most allosteric studies have focused on thermodynamic properties, in particular, substrate binding affinity. Changes in substrate binding

Radiation and Environmental Biophysics, 1999
Nucleotide conformation and dynamics are important for the study of radiation damage to DNA at the atomic level. It is necessary to study not only normal oligonucleotide structure but also those containing modified bases which result from interaction with OH-radicals. There are now over 8000 atomic coordinate entries in the Brookhaven Protein Data Bank,

Hyaluronan chain conformation and dynamics
Carbohydrate Research, 2005An overview of the present state of research in the field of hyaluronan chain conformational aspects is presented. The relationship between structure and dynamics are illustrated for a series of hyaluronan oligomers. Conformational characteristics of hyaluronan chains are discussed, together with the dynamic chain patterns, evaluated by using a ...

Dynamic α‐helices: Conformations that do not conform
Proteins: Structure, Function, and Bioinformatics, 2007AbstractStructural transitions are important for the stability and function of proteins, but these phenomena are poorly understood. An extensive analysis of Protein Data Bank entries reveals 103 regions in proteins with a tendency to transform from helical to nonhelical conformation and vice versa.

Conformational dynamics through an intermediate
The Journal of Chemical Physics, 2014The self-assembly of biological and synthetic nanostructures commonly proceeds via intermediate states. In living systems in particular, the intermediates have the capacity to tilt the balance between functional and potentially fatal behavior. This work develops a statistical mechanical treatment of conformational dynamics through an intermediate under

Conformational Dynamics of a Bispyridinium Cyclophane
The Journal of Organic Chemistry, 2003A complete study of the conformational behavior of 4,8-diaza-3(1,4),9(4,1)-dipyridina-1,6(1,4)-dibenzenacyclodecaphan-3(1),9(1)-bis(ilium) bishexafluorophosphate is described. This study allows us to conclude that the process observed by which the different chemical shifts of the pyridinium protons show coalescence at a high-temperature 1H NMR is the ...
