The recent discovery of metamorphic proteins, which can switch between multiple conformations under native conditions, has challenged the well-established one sequence-one structure paradigm of protein folding. This is exemplified in the C-terminal domain of the multidomain transcription factor RfaH, which converts from an ?-helical coiled-coil conformation in its autoinhibited state to a ?-barrel conformation upon activation. Here, we use multisite line shape analysis of ^(19)F NMR-monitored...

Comprehensive analysis of NMR data using advanced line shape fitting
Abstract
NMR spectroscopy is uniquely suited for atomic resolution studies of biomolecules such as proteins, nucleic acids and metabolites, since detailed information on structure and dynamics are encoded in positions and line shapes of peaks in NMR spectra. Unfortunately, accurate determination of these parameters is often complicated and time consuming, in part due to the need for different software at the various analysis steps and for validating the results. Here, we present an...

NMR line shape analysis of a multi-state ligand binding mechanism in chitosanase
Abstract
Chitosan interaction with chitosanase was examined through analysis of spectral line shapes in the NMR HSQC titration experiments. We established that the substrate, chitosan hexamer, binds to the enzyme through the three-state induced-fit mechanism with fast formation of the encounter complex followed by slow isomerization of the bound-state into the final conformation. Mapping of the chemical shift perturbations in two sequential steps of the mechanism...
