[ccp4bb] X-Ray versus NMR Structure

2008-11-13 Thread David Chenoweth
Dear all, Does anyone know of a good published reference that describes the pros and cons of X-ray versus NMR structure determination. Something specific to nucleic acids would even be better. I've noticed that several papers describe NMR structures as "atomic resolution structures" and I

Hi Ian, All - I was just in a discussion about TLS and one thing that came out that I hadn't been aware of is that for the Biso restraints Refmac restrains the difference between the 'residual' Bs, i.e. with the TLS contributions subtracted, not the 'total' Bs. Now it seems to me that this isn'

This has been reviewed, although a few years ago now. In most cases the linker between the fusion tag and the protein of interest had to be shortened and engineered.

Hi, I didn't want to get into this because so many good comments and suggestions have already been made - but I guess I will make a wordy and effusive comment of my own :) In my opinion, the question of how *specific* tags (His, c-Myc) influence crystallization is somewhat misleading. The questio
