Membrane protein structures: the known world expands.
The structure determinations of the cytochrome bc1 complex and the prokaryotic potassium channel demonstrate that a wider range of membrane proteins are now amenable to study by X-ray crystallography. Furthermore, the structures of porins and interfacial membrane proteins show that membrane structural biology is becoming a mature and productive field.
