It is demonstrated here how the secondary structure and dynamics of transmembrane helices, as well as surface residues, such as interhelical loops and N- or C-terminus of bacteriorhodopsin (bR) in purple membrane, can be determined at ambient temperature based on very simple (13)C-NMR measurements, together with a brief experimental background. In contrast to the static picture of bR, currently available from X-ray diffraction or cryo-electron microscopy, the structure consists of dynamically heterogeneous domains which undergo various types of local fluctuations with a frequency range of 10(2)--10 (8) Hz. The significance of this picture is discussed in relation to the biological function of this protein.
