[ccp4bb] Reminder for Post-doc vacancy at Diamond -closing date 22-sept-11

2011-09-13 Thread Martin Walsh
Dear all just a reminder as this was posted during holiday period...we have a vacancy for a 1 year post-doc at diamond which brings together crystallography, 2D-IR spectroscopy and biology. Full details in link below: http://www.mis.strath.ac.uk/Personnel/open/r702011.htm informal discussions c

[ccp4bb] Structure problem

2011-09-13 Thread #HEW KAI LI KELLY#
Hi, I am facing some problems in solving my structure now, so I am wondering if anyone is able to give me any tips and tricks on this matter. My protein-DNA complex structure diffracted to 1.5A. There are 4 missing residues, 2 on each terminal. There is no twinning in the data. The angles, the

Hi there, In crystallography there are so many places where you can have problems (and need to solve these problems) that I cannot list them all. "There is no twinning in the data" - you probably mean "the data does not seem to indicate the presence of twinning but there might be twinning";

[ccp4bb] neutron diffraction 'difference' map?

2011-09-13 Thread Francis E Reyes
Hi all Suppose you have a high resolution xtal structure (from usual x-ray diffraction) and you wanted to verify the location of a ligand. You can purchase a heavy atom isotope version of the ligand. [1] Is it possible to do a neutron diffraction difference map (where you simply calculated Fo

[ccp4bb] Last beamtime on BM14 before ESRF Upgrade shutdown period

2011-09-13 Thread hassan belrhali
Dear all, the period November - December 2011 is opened for beamtime e-proposal requests at the BM14 MAD MX Beamline (ESRF, Grenoble, France) . This is the last period time before the ESRF Upgrade winter shutdown [Dec-5th 2011 -- April 30th 2012 ]. Thank you to submit your proposal
