The backbone dynamics of uniformly (15)N-labelled fragments (residues 1-71 and 1-36) of bacterioopsin, solubilized in two media (methanol-chloroform (1:1), 0.1 M (2)HCO(2)NH(4), or SDS micelles) have been investigated using 2D proton-detected heteronuclear (1)H-(15)N NMR spectroscopy at two spectrometer frequencies, 600 and 400 MHz. Contributions of the conformational exchange to the transverse relaxation rates of individual nitrogens were elucidated using a set of different rates of the CPMG… CONTINUE READING
