Re: X Ray crystallography & transmembrane proteins

... proteins in toto is one of the “holy grails” of crystallography. There is no general way to do it and of the few cases that have succeeded, two (rhodopsin and F1-ATPase) won Nobel Prizes. Transmembrane regions of membrane and integral membrane proteins tend to be very hydrophobic. When you isolate ...
