Geny,
Unfortunately, it is a very common case. In our practice, we have 20-40%
of protein crystals that show this kind of diffraction. We still call
them crystals because they often look beautiful, with nice edges and
planes. My understanding is that the protein molecules are not arranged
ord
Is it a crystal if there are no reflections? Aren't Bragg reflections a
necessary and sufficient condition for calling something a crystal? Ron

I agree that density looks dubious, the B-factor distribution among DNA atoms
is odd (sudden shifts from blue to red) and the little wwPDB bar charts are on
the red side.
But what about the density for the protein?
