I agree on both counts. Some classes of proteins are very difficult to isolate and crystallize.
This will result in both few template structures for homology modeling and few structures that
can be determined by X-ray crystallography/NMR. The second point is what I meant with the
precision versus 'biologically relevant accuracy' issue in one of my previous posts.
