[ccp4bb] Off topic: A new platform (AnoXtal) for anaerobic protein crystallization

2013-12-13 Thread Juan Fontecilla
Dear all, please note: *AnoXtal: a new platform dedicated to protein crystallization under anaerobic conditions.* ** ** ** The Metalloproteins Group of the Institut de Biologie Structurale will receive demands for anaerobic protein crystallization, from both the academic and private

Rhys, We have solved several structures in our lab using bicelles (all beta-barrels). It is generally the case that we want to minimize excess detergent for crystallization and it is the same for bicelles. At least for our cases, we have not done anything extra to remove excess detergent

Hi all; I have crystal of membrane protein (110 kDa) in several different conditions. I optimized several of them and tested it for their diffraction. It does not goes behind 10A at CLS and SSRL. The protein is purified by two steps nickel and gel filtration. The crystal grow very fast and reach

[ccp4bb] Wrong Space Group?

2013-12-13 Thread D Bonsor
Dear all, I have collected ~160 degrees of data on a new crystal form of a protein which has already been solved. Data was processed with XDS and reindex, scaled and truncated with Aimless. Both XDS and Pointless suggested a Laue group of P6/mmm with a possible space group of P6122 or P6522.

Hi Rhys, I hope you are well. The JOVE article for bicelles is nice, plz check the video. There is a table in the text section showing some structures that originated from crystals grown at 4-7 % bicelle conc. using not only the DMPC/CHAPSO mixture... The other parameter that everyone tries is

2.8 is not a terrible resolution to try out Buccaneer or Parrot. Your terrible R-factor might be due to a shift in residues perhaps ? Your After-building map does not show much of a side chain density to judge if you are in frame or off. But the elongated helix is in my eyes convincing enough.
