Default Following protein folding in real time using NMR spectroscopy.

Following protein folding in real time using NMR spectroscopy.

Nat Struct Biol. 1995 Oct;2(10):865-70

Authors: Balbach J, Forge V, van Nuland NA, Winder SL, Hore PJ, Dobson CM

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 dichroism. The NMR spectrum of the transient intermediate resembles closely that of the well characterized stable molten globule state formed at low pH. The results suggest that NMR can play a key role in describing at an atomic level the structural transitions occurring during protein folding.

Kinetic analysis of protein aggregation monitored by real-time 2D solid-state NMR spectroscopy
Kinetic analysis of protein aggregation monitored by real-time 2D solid-state NMR spectroscopy Abstract It is shown that real-time 2D solid-state NMR can be used to obtain kinetic and structural information about the process of protein aggregation. In addition to the incorporation of kinetic information involving intermediate states, this approach can offer atom-specific resolution for all detectable species. The analysis was carried out using experimental data obtained during aggregation of the 10.4 kDa Crh protein, which has been shown to involve a partially unfolded intermediate...

J Mol Biol. 2003 May 16;328(5):1161-71 Authors: Mizuguchi M, Kroon GJ, Wright PE, Dyson HJ At low ionic strength, apoplastocyanin forms an unfolded state under non-denaturing conditions. The refolding of this state is sufficiently slow to allow real-time NMR experiments to be performed.
