Dr. Susan Buchanan (NIDDK): Crystallization of Integral Membrane Proteins X-ray crystallography has become a very powerful tool for determining the structures of integral membrane proteins, with almost 200 unique membrane protein structures solved as of December 2007 (for a complete list, see Stephen White’s summary at http://blanco.biomol.uci.edu/Membrane_Proteins_xtal.html). However, membrane protein structures still represent less than 1% of all structures in the PDB. The major bottlenecks in the field are the expression of sufficient quantities of functional membrane proteins and the growth of well ordered crystals for X-ray analysis. This short review covers only aspects pertaining to crystallization. Our approach to membrane protein crystallization was recently written up for Current Protocols in Protein Science (Unit 17.9, available from the NIH library website). An interesting review has been written by Patrick Loll1. (Full Article) Item
