Redesigned BioSync Website is a Valuable Resource for Structural Biologists

BioSync

Originally started as a website to provide basic information about the small number of synchrotron beamlines used for macromolecular crystallographers, BioSync has metamorphosed into a structural biologists' guide to high-energy data collection facilities. This newly redesigned web resource includes detailed information about the more than 130 beamlines worldwide that are used to collect experimental data on biological macromolecules. The beamline scientists provide information on the actual conditions of the beamline for data collection and the services offered to users (e.g., remote data collection and robotics for crystal screening and mounting).

Reconstitution of a Three-Component Membrane Protein Complex Using Wheat Germ Cell-Free Technology

MP fold

Wheat germ cell-free translation has been shown to be an effective method to produce integral membrane proteins in the presence of unilamelar liposomes. A three-component membrane protein complex was reconstituted using wheat germ cell-free technology. The data strongly support the utility of wheat germ cell-free technology to produce active and correctly folded integral membrane proteins.
