Re: [ccp4bb] I222 - P22121 space-group ambiguity

2014-10-13 Thread Jodie Johnston
Hi Florian, Not sure if this is helpful or not but I have a particular protein that seems to be either P22121 (with 2 molecules) or I222 (with one molecule). Not from the same drop but crystallised in similar conditions but with different small molecules bound. In many cases the crystals

[ccp4bb] Is it possible for a ligand cif file from the CCP4 library to contain errors ?

2013-10-29 Thread Jodie Johnston
Hi I wanted to check is it possible that there could be errors in the library cif files associated with CCP4 and coot ? I have noticed a couple of potential errors in a ligand cif file from the CCP4 library. Perhaps it is my error - I shall need to triple check it again but, if it

, except for the matter if there is 'right' and 'wrong' in science or rather 'good' and 'bad' models, Garib Murshudov maintains the cif-library and if you send him a compilation of possible fixes he would surely appreciate your input. Best, Tim On 10/29/2013 10:15 AM, Jodie Johnston wrote: Hi

Re: [ccp4bb] Off topic: His-tag purification

2012-01-15 Thread Jodie Johnston
Hi Theresa, I am right in thinking the protein construct you are using is just 8 His residues added to 90kDa ? It could be (if this is the case) that the tag is not accessible for binding to the Ni column. Sometimes you need a linker sequence between the protein for the His-tag to coordinate
