要旨:
In spite of several great breakthroughs, the overall rate of progress in determining high-resolution structures of membrane proteins has been slow. This is entirely due to the scarcity of suitable, well-ordered crystals. Most membrane proteins are multimeric complexes with a composite molecular mass in excess of 50000 Da which puts them outside the range of current solution NMR techniques. For the foreseeable future, detailed information about the structure of large membrane proteins will therefore depend on crystallographic methods.
