Thanks for all suggestions. I am going to P32-label the RNA and see if it runs as a single species on the gel and if not, I'll do the HPLC. Alex On Mon, May 20, 2013 at 11:16 AM, Eugene Valkov eugene.val...@gmail.comwrote: Hi Alex, If you do not have access to HPLC equipment, another

[ccp4bb] list/library of most commonly co-crystallized ligands/solvents and/or their electron density shapes

2013-05-21 Thread 孙庆祥
hi all, Sorry if this has been asked before. I wonder if there is an list or library of most commonly co-crystallized ligands(or solvent molecules) available? Better if the electron density maps of the ligands are also shown with different resolutions. That could help a lot for an

Hi Jeremy, Given the large number of different kinds of ligands that are observed (either from crystallization, purification conditions or endogenous), I think it will be really difficult to assign just by visual and manual comparison with a standard set, especially for inexperienced

[ccp4bb] DNA version converter

2013-05-21 Thread Ed Pozharski
Does anyone have a script to convert pdb file with DNA atom records from v3 back to v2? I can certainly right my own and asking only if you already have it written. Strictly speaking, this is not ccp4-related - apparently, buster expects the old format. Cheers, Ed. -- Oh, suddenly

I'm not sure that a library of ligand electron density would be an entirely good thing. I guess something small like an acetate or DMSO would be relatively consistent but larger things like PEGS or even glycerols are going to be dependent on the nature of the binding site. A good example would be
