command line molprobity tools
by Engin Özkan 27 May '13

27 May '13

Hi everybody, I want to create a comprehensive, human-readable log file by running validation using molprobity tools within phenix command-line. I do not have structure factors/maps. Apparently, the GUI runs validation through phenix.model_vs_data (according to the .eff file), but in command-line, I cannot get phenix.model_vs_data to run without an mtz/hkl. I guess I could provide it a fake data file, and then set the comprehensive flag to "True"? BTW, the log file produced by the GUI is not comprehensive at all. I could not find a related mmtbx or cctbx function either. Another mentioned tool, phenix.validate, does not even exist in my installation (dev 1361).

conflicting bond_simple restraints
by Jianxun Qi 23 May '13

23 May '13

Hi, I had a phosphoserine (SEP) in my structure that is attached in this message. The data_link file for SEP already exists in the mon_lib (data_link_SEPC-N) and the corresponding cif_link I used is as follow: refinement.pdb_interpretation { apply_cif_link { data_link = "SEPC-N" residue_selection_1 = "chain C and resname PHE and resid 3" residue_selection_2 = "chain C and resname SEP and resid 4" } apply_cif_link { data_link = "SEPC-N" residue_selection_1 = "chain C and resname SEP and resid 4" residue_selection_2 = "chain C and resname ARG and resid 5" } } When I run the phenix.refine (my version is phenix-1.8-1069), it said conflicting bond_simple restraints: Sorry: Conflicting bond_simple restraints: 1. definition from: residues: PHE + SEP 2. definition from: residues: PHE + SEP atoms: "ATOM 3121 C PHE C 3 .*. C " "ATOM 3192 N SEP C 4 .*. N " Has anyone ever experienced this case before? Any hints are welcome. Regards Jianxun Qi May 22,2013

Ca occupancy in multiple soaked structures
by Daniel Slade 23 May '13

23 May '13

Hi Everyone, I have a complex case of data analysis I would love some opinions on. I have a group of structures of a protein that binds 6 calciums, and we want to know the order/concentration at which they fill. The crystals were soaked with calcium from 0-10 mM and all are 1.6-2.1 A in resolution. I determine the order of the calcium binding, and now I am working on the percent occupancy at each concentration. To do this, I have removed the calciums, and then performed simulated annealing for each structure from 2.1-30A resolution to 'normalize' them. I then look at the omit map and scroll out to find the peak sigma intensity of where the calciums should be. The curves fit very well for each calcium, and the numbers correspond well with other solution studies we have. My thought is that I need to normalize this in another way, so I thought choosing a water molecule that is present in all of the structures and removing it, then performing simulated annealing would be a good idea to normalize the peak intensity for each calcium soak concentration, since this water molecule shouldn't change occupancy. Is this the proper way to do this, or can you guys suggest a better way to go about this. I also looked at B factor and e/A3, but that isn't as consistent as peak sigma. Thanks in advance.

Workshop - The Future of Microfocus Protein Crystallography - 24-25 September, 2013, Lund, Sweden
by Marjolein Thunnissen 22 May '13

22 May '13

Dear all, I would like to announce a workshop on "The Future of Microfocus Protein Crystallography" which will take place at the MAX IV User meeting on the 24th and the 25th of September, 2013, in Lund, Sweden. Recent developments within protein crystallography methods in combination with the possibilities offered by the new upcoming synchrotron sources such as the MAX IV 3 GeV storage ring make possible exciting new ways of carrying out research within structural biology. Small microfocus beamlines with a very high flux and increased coherence will make new types of experimentation possible. The scientific possibilities will be highlighted through a series of talks by experts showing the impact of the new type of X-ray sources and microfocus beamlines on research within structural biology. The new generation of microfocus beamlines will also set a high demand on instrumentation and suitable software. For example, data collection will potentially be very fast (in milliseconds) and radiation damage will allow only a limited amount of data to be collected from each sample. New technical solutions for sample handling and presentation, data processing methods and more will be needed for these types of experiments, and these will also be presented and discussed at the workshop. Confirmed speakers include David Stuart, Daniel Wacker, Simone Weynand, Jens Preben Morth, Tove Sjögren, Richard Neutze, Janet Smith, Alke Meentz, Alexei Soares, Thomas White and Clemens Schulze-Briese The workshop is part of a process to obtain an updated proposal for the possible Phase 2b beam line MicroMAX at the upcoming new 3 GeV storage ring of MAX IV in Lund. This workshop should give the user community an opportunity to explore the scientific possibilities of a new generation of microfocus beam lines, but also it will give them the chance to contribute with specific input on their own experimental demands on the beam line. The workshop is part of the MAX IV laboratory user meeting. Registration will be through the user meeting website which will open for registration soon. Further information on this workshop can be found at https://www.maxlab.lu.se/node/1609 and for the MAX IV user meeting at https://www.maxlab.lu.se/um13 .
