Hi folks, crystallized a lot of SRP RNAs - never had success with synthetic RNA, even with small 30mers T7 RNA pol in vitro transcribed was always extremely better - moreover: I always use a 3' hammerhead which yields in the end 100% pure material in mg amounts - Kiyoshi Nagais protocol is a

Dear CCP4BB Thank you to everyone who sent me answers to my problem. I obtained the average B factors using Baverage. It was also suggest that I could have used act, a script from the CCP4 homepage, MOLEMAN, phenix.model_vs_data or copying the data into Excel using the paste special option and

[ccp4bb] Off topic: How to identify a unknown ligand

Dear all, Sorry for this off topic question. We are working on protein/inhibitor complex structure although we can not get our inhibitors in. However, we did find a strange density at the active site, it looks really like GSH, the natural co-enzyme of thiis protein.We tried to use very simple

[ccp4bb] Crosslinking of Protein-Protein complex for crystallisation

2011-03-14 Thread Catrine Berthold Siƶberg
Dear CCP4bb, I am trying to solve the structure of a protein-protein complex. The two proteins are co-expressed and co-purified and I get a homogeneous 1:3 complex, which is the predicted composition. I get several hits using commercial crystallisation screens (including the MD ProPlex

Dear Catrine can you comment on the pH range of your crystallization hits compared to the pH of the sample you use for your crystallization trials? The pH can be a major issue depending on the nature of the interaction interface. best regards Savvas On 14 Mar 2011, at 13:21, Catrine

Hi Michael, If the problem is the absence of a purine on the 5' end, try using the Marc Dreyfus' mutant T7 RNA polymerase. It can accommodate any nucleotide at the 5' end. Guillerez, J., Lopez, P. J., Proux, F., Launay, H., and Dreyfus, M. (2005) A mutation in T7 RNA polymerase that
