in genome sequences and predicting the membrane topology of
membrane proteins. When it comes to predicting membrane-protein
3D structure, however, there are no automatic methods available,
and models have to be built on a case-by-case basis taking as much
experimental information as possible into account (Elofsson, von
Heijne, 2007).
