HIGH RESOLUTION X-RAY STRUCTURE OF AN EARLY INTERMEDIATE IN THE BACTERIORHODOPSIN PHOTOCYCLE
Overview
Bacteriorhodopsin is the simplest known photon-driven proton pump and as, such provides a model for the study of a basic function in bioenergetics., Its seven transmembrane helices encompass a proton translocation pathway, containing the chromophore, a retinal molecule covalently bound to lysine, 216 through a protonated Schiff base, and a series of proton donors and, acceptors. Photoisomerization of the all-trans retinal to the 13-cis, configuration initiates the vectorial translocation of a proton from the, Schiff base, the primary proton donor, to the extracellular side, followed, by reprotonation of the Schiff base from the cytoplasm. Here we describe, the high-resolution X-ray structure of an early intermediate in the, photocycle of bacteriorhodopsin, which is formed directly after, ... [(full description)]
