Hi Tassos, Tim, I wonder why would you or anyone on this list worry whether biological questions that can be asked and answered with structures are relevant to justify the resources? I think there is abundant evidence that this is the case. Unless your point is that crystallography is now dead for all practical purposes... then yes, I fully agree :-) It would however be wrong to erase its historical contribution to understanding biology.
