Real‐Time Detection of Protein–Water Dynamics upon Protein Folding by Terahertz Absorption Spectroscopy

Abstract

Take a look around: Kinetic terahertz absorption (KITA) spectroscopy has been used to monitor the attenuation and phase shift of a terahertz electric field transmitted through a protein during refolding. Comparison with data from fluorescence, circular dichroism, and small angle X-ray scattering shows that KITA monitors rearrangements of the hydration water–protein interactions during early collapse and secondary structure formation.
