Structural Bases of Membrane Protein Functioning

Sa？etak Nowadays membrane proteins arouse a keen interest as direct participants of numerous vitally important processes in the living cell. Of special significance here are the proteins involved in : bioenergetic and transport functions as well as in transformation and transfer of various internal stimuli. These are various ATP ases, fast sodium channels of excitable membranes and retinally-contained pigments, bacteriorhodopsin and animal rhodopsin. The present report is concerned with current advances in the study of the chemical nature and spatial organization and functioning of these systems
