Advances in structural and functional analysis of membrane proteins by electron crystallography.

چکیده
Electron crystallography is a powerful technique for the study of membrane protein structure and function in the lipid environment. When well-ordered two-dimensional crystals are obtained the structure of both protein and lipid can be determined and lipid-protein interactions analyzed. Protons and ionic charges can be visualized by electron crystallography and the protein of interest can be captured for structural analysis in a variety of physiologically distinct states. This review highlights the strengths of electron crystallography and the momentum that is building up in automation and the development of high throughput tools and methods for structural and functional analysis of membrane proteins by electron crystallography.

متن کاملTwo-dimensional crystallization of membrane protein complexes for structure-function studies by electron crystallography
Membrane proteins comprise one of the major challenges in structural biology. Membrane protein complexes pose particular difficulties because they not only require careful solubilization, but additionally the structural, as well as functional integrity, of the entire complex needs to be maintained. Electron crystallography of two-dimensional (2D) crystals is an important emerging approach in th...
