Following protein folding in real time using NMR spectroscopy.
The refolding of apo bovine alpha-lactalbumin has been monitored in real time by NMR spectroscopy following rapid in situ dilution of a chemically denatured state. By examining individual resonances in the time-resolved NMR spectra, the native state has been shown to emerge in a cooperative manner from an intermediate formed in the dead-time of the experiments. The kinetics of folding to the native state are closely similar to those observed by stopped-flow fluorescence and near-UV circular d...Expand abstract
