Journal ArticleDOI
Model for the structure of bacteriorhodopsin based on high-resolution electron cryo-microscopy.
TL;DR: A complete atomic model for bacteriorhodopsin between amino acid residues 8 and 225 has been built and suggests that pK changes in the Schiff base must act as the means by which light energy is converted into proton pumping pressure in the channel.
Journal ArticleDOI
Analysis of high-resolution electron diffraction patterns from purple membrane labelled with heavy-atoms
T. A. Ceska,Richard Henderson +1 more
TL;DR: It is concluded that, with the present accuracy of data collection and the present magnitude of delta F/F available for the derivatives, the phasing power is too small and the phases that are obtained are not sufficiently accurate to provide a reliably interpretable map.
Journal ArticleDOI
An atomic model for the structure of bacteriorhodopsin.
TL;DR: A complete atomic model for bacteriorhodopsin between amino acids 8 and 225 has been built, using bulky aromatic side-chains of phenylalanine, tyrosine and tryptophan as guide points as well as a very dense feature which is the Bionone ring of the retinal chromophore.
Journal ArticleDOI
Electron diffraction analysis of the M412 intermediate of bacteriorhodopsin
TL;DR: Movements of a few amino acid side chains, and repositioning of atoms of the retinal group and the associated lysine side chain after trans-cis isomerization, are the most probable causes of the observed intensity changes in the M state.
