[ccp4bb] offtopic: effect of compound impurities on ITC?

2010-08-24 Thread Francis E Reyes
Hi All I'm curious the effect of small impurities in commercially synthesized compounds on ITC and its analysis. Say if compound Y is the high affinity binder, but you make a derivative that differs from a single functional group from Y (you used Y to make this new compound) and you

Hi,   If your are talking about proteins or protein subunits, this means that you are making polymers of nY, and Y becames the monomer. So in this case, I will not consider Y as an impurity.   If I get you right, then size exclusion chromtography is good option to separate the monomers from

Hi, I have an undergraduate student collecting information for the development of a database of sulfur-SAD phased structures including data collection and other experimental parameters for his semester project. Since mining the PDB for this information has proven difficult I am asking members

[ccp4bb] TLSMD Alignments

2010-08-24 Thread Michael Thompson
Hi All, I have a question for those of you familiar with the TLSMD webserver. I am working on a structure with slightly imperfect 3-fold rotational NCS. My most recent .pdb file has been generated using Refmac (followed by a little tinkering in Coot), and during refinement I have been imposing

Dear Micheal, As you say, the effect is probably arising from the different packing environment of your NCS-related molecules. Once you've taken TLS groups into account NCS restraints might even perform better. Cheers, Roberto On 24 Aug 2010, at 21:15, Michael Thompson wrote: Hi All, I
