Millisecond Protein Folding Studied by NMR Spectroscopy

Proteins are involved in virtually every biological process and in order to function, it is necessary for these polypeptide chains to fold into the unique, native conformation. This folding process can take place rapidly. NMR line shape analyses and transverse relaxation measurements allow protein folding studies on a microsecondto- millisecond time scale. Together with an overview of current achievements within this field, we present millisecond protein folding studies by NMR of the cold shock protein CspB from Bacillus subtilis.
