This suggests that Pdx (and other ferredoxins) is a less rigid system than monohemes, and that redox-linked changes in conformation, and/or conformational dynamics, impart to these proteins the ability to interact with a number of redox partners.
By comparing both changes in conformation and crystallinity during thermal annealing, we found that the trans conformer increases continuously while the degree of crystallinity levels off during the later stage of annealing.
The first stage comprises physicochemical transformation (dehydration, melting, changes in conformation of molecules, initial defragmentation etc).
The changes in conformation of PMHS chains were monitored with the UV absorption spectrum.
A fluorescence-quenching pair is used to report changes in conformation induced by ligand binding.
Circular dichroism and molecular modelling have been used to study changes in conformation.
The observed changes in conformation of YfiB and the results of mutagenesis suggest a mechanism by which YfiB sequesters YfiR.
For pre-ordered structures we expect some changes in mobility too because of the changes in conformation on pre-ordering.
We observed that the enzyme-polymer conjugates retained temperature-dependent changes in conformation while still maintaining enzyme function.
Although, reduced activity in the enzyme may reflect changes in conformation of the key amino acid residues around the active site of the enzyme upon immobilization [41].
The first of these concerns reversible pressure induced changes in conformation of the protein lysozyme with consequent changes in its affinity for N-acetyl-D glucosamine.
