Re: [ccp4bb] Do you have this type of diffraction pattern?

2017-11-30 Thread Ivan Shabalin
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 On Thu, 30 Nov 2017, Geny wrote: ​Dear EveryOne, ​​I recently tried to collect the diffraction data, but unluckily, the diffraction patter is atta

2017-11-30 Thread Phoebe A. Rice
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? The structure is of a hexameric helicase with with dsDNA going through the h
