Most biological reactions rely on interplay between binding and changes in both macromolecular structure and dynamics. Practical understanding of this interplay requires detection of critical intermediates and determination of their binding and conformational characteristics. However, many of these species are only transiently present and they have often been overlooked in mechanistic studies o...

Properties of supramolecular nanostructures are mediated by conformational, exchange, and water dynamics. Here we review experimental methods recent reports dynamics characterization small molecule nanomaterials.

the surface parameter of nanoparticles such as hydrophobicity and a hydrophilicity on protein structure and function is very important. in this study, conformational changes of glucose oxidase (gox) in the mercaptopurine: gnps and 11-mercaptoundecanoic acid: gnps as a hydrophobic and a hydrophilic gnps surface was investigated by various spectroscopic techniques, including: uv-vis absorption, f...

PAS and related GAF are ubiquitous highly versatile sensing domains that associate a range of signaling effectors. Each year, new bacterial characterized but genomes analysis suggests this list is far from complete. This review aims to synthesize the current state knowledge on structure activity metal-binding PAS/GAF domain proteins. can bind disparate metal cofactors with very precise coordina...

Sixty-six haplotypes at a locus containing a simple dinucleotide (CA)n microsatellite repeat were isolated by PCR-single-strand conformational polymorphism from populations of the horseshoe crab Limulus polyphemus. These haplotypes were sequenced to assess nucleotide variation directly. Thirty-four distinct sequences (alleles) were identified in a region 570 bp long that included the microsatel...

The conformational behavior of monosubstituted tri-methylsilyle ethynyl Derivative of Cal ix[4]arene as a newgeneration of Caliarene was compared with tetra alkylated calyx[4]arene. The most important conformationalphenomena in these compounds which are pinched cone interconversion process were done by semi-empiricalmethod and ab initio calculations with Gaussian 98w programming.
