Abstract
Fourier transform infrared difference spectroscopy was used to study the effect of millimeter-range electromagnetic radiation on the structure of bacteriorhodopsin under lighting conditions. A detailed analysis of the Fourier IR spectra revealed pronounced structural changes in the region of amide I, amide II and rearrangement of the hydrogen bond network. The well-resolved peaks of the amide bands made it possible to recognize two different components (α-I and α-II) of the α-helical conformation of the opsin. Irreversible conformational changes of bacteriorhodopsin in purple membranes detected by Fourier IR difference spectroscopy suggested that microwaves induced structural rearrangements of proteins unrelated to temperature.

期刊介绍:
Biophysics is a multidisciplinary international peer reviewed journal that covers a wide scope of problems related to the main physical mechanisms of processes taking place at different organization levels in biosystems. It includes structure and dynamics of macromolecules, cells and tissues; the influence of environment; energy transformation and transfer; thermodynamics; biological motility; population dynamics and cell differentiation modeling; biomechanics and tissue rheology; nonlinear phenomena, mathematical and cybernetics modeling of complex systems; and computational biology. The journal publishes short communications devoted and review articles.
