Ph.D. position at Lund University
by Derek Logan 07 Jan '13

07 Jan '13

A 4-year PhD position is available in the groups of Dr. Derek Logan and Prof. Ulf Ryde at the Dept. of Biochemistry and Structural Biology and the Dept. of Theoretical Chemistry at Lund University, Sweden. The project is sponsored by the European Spallation Source and will also involve the participation of ESS scientists. The PhD student will work on structural and theoretical studies of protein-ligand interactions, using the carbohydrate binding protein galectin-3 as a model system. Structural studies will be conducted principally using neutron crystallography in combination with X-ray crystallography at very high resolution (< 0.9 Å). The work will include production of crystals of suitable size for neutron diffraction, data collection at various neutron sources around the world, data processing and modelling. The theoretical studies will be conducted in Ulf Ryde's group at Theoretical Chemistry. We will develop methods to combine crystallographic refinement and quantum mechanical calculations. In addition, we perform molecular dynamic simulations and estimates of binding affinities using free-energy perturbation. The project is part of a larger network at Lund University including organic chemists, medical scientists and NMR experts, dedicated to a fundamental understanding of protein-ligand interactions in general and galectin inhibition in particular. The candidate must have bachelor's degree in an appropriate subject (preferably chemistry) and should ideally have previous experience in structural biology, both theoretical and practical. The candidate should also have good knowledge of theoretical chemistry. Experience of quantum chemistry, statistical mechanics and simulations is an advantage. The deadline for application is 31st January 2013. For more information on the eligibility requirements, please see: http://admin.lu.se/o.o.i.s?id=22598&Dnr=511988&Type=E Application should be made using the link in the right hand column of this web page.

The West Coast Protein Crystallography Workshop is fast approaching (March 17th). The site (wcpcw.org) is up, registration is open and the option to pay by credit card is now available. The conference has a long tradition of methods development and organized as such to facilitate discussion and colloboration. We are especially interested in having speakers that are doing the ‘real’ work - graduate students, postdocs and staff scientists! We are also honored having Prof. Wayne Hendrickson as our keynote speaker. Prof. Hendrickson has made seminal contributions to the field including efforts in phase combination (Hendrickson-Lattman coefficients), incorporation of stereochemical constraints in protein refinement (e.g., PROLSQ – the predecessor to many of the refinement programs we now use), and the development of MAD phasing (including the development of selenomethionine incorporation). In addition, Prof. Hendrickson’s lab has produced a large number of biologically important structures including the HIV caspid GP120 bound to CD4, the first tyrosine kinase structure (Lck), and many, many others. We look forward to seeing you in Monterey! Best, John

Anomalous group refinement question
by Pawel Grochulski 03 Jan '13

03 Jan '13

Dear all, Instruction says: Anomalous groups refines the anomalous coefficients f' and f'' for anomalously scattering atoms such as Se or heavy metals; it is only appropriate if you have anomalous data (I+/I- or F+/F-). How do I indicate which atoms to be considered? Thank you for your help. Happy New Year. Pawel ____________________ Dr. Pawel Grochulski, D.Sc.

Problem with anomalous scattering factor refinement
by Subhani Bandara 27 Dec '12

27 Dec '12

Hi all, I've been trying to refine a structure with anomalous data with anomalous scattering factors. After some refinements without anomalous scattering factor refinement, I used the data.mtz file and original reflection file in reflection file editor to get the anomalous data merged with Rfree flags. When I tried to use this file with a pdb file (deleted hexadigest remark) and a cif file for ligands, the refinement ends with the following error at the end of the 3rd refinement cycle (I have only 3 cycles for a refinement). I was able to run a similar refinement with anomalous scattering factors for another structure without a problem. One difference in this structure is that this has NCS and the previous one didn't. I am using dev-1243 GUI. RuntimeError : scitbx array_family range error Traceback: File "/Applications/PHENIX-dev-1243/Contents/phenix-dev-1243/cctbx_project/libtbx/thread_utils.py", line 234, in run return_value = self._target(self._args, self._kwargs, self._c) File "/Applications/PHENIX-dev-1243/Contents/phenix-dev-1243/cctbx_project/libtbx/runtime_utils.py", line 87, in __call__ result = self.target() File "/Applications/PHENIX-dev-1243/Contents/phenix-dev-1243/cctbx_project/libtbx/runtime_utils.py", line 66, in __call__ result = self.run() File "/Applications/PHENIX-dev-1243/Contents/phenix-dev-1243/phenix/phenix/refinement/runtime.py", line 69, in run refine_object = self._run(args, callback) File "/Applications/PHENIX-dev-1243/Contents/phenix-dev-1243/phenix/phenix/refinement/runtime.py", line 85, in _run call_back_handler=callback) File "/Applications/PHENIX-dev-1243/Contents/phenix-dev-1243/phenix/phenix/refinement/command_line.py", line 169, in run map_manger.write_files() File "/Applications/PHENIX-dev-1243/Contents/phenix-dev-1243/phenix/phenix/refinement/driver.py", line 1735, in write_files map_coeff_dataset=self.write_mtz_file(), File "/Applications/PHENIX-dev-1243/Contents/phenix-dev-1243/phenix/phenix/refinement/driver.py", line 1724, in write_mtz_file pdb_hierarchy=self.refine_object.model.pdb_hierarchy()) File "/Applications/PHENIX-dev-1243/Contents/phenix-dev-1243/cctbx_project/mmtbx/maps/__init__.py", line 500, in __init__ pdb_hierarchy = pdb_hierarchy) File "/Applications/PHENIX-dev-1243/Contents/phenix-dev-1243/cctbx_project/mmtbx/maps/__init__.py", line 428, in map_coefficients_from_fmodel sharp = params.sharpening).map_coeffs File "/Applications/PHENIX-dev-1243/Contents/phenix-dev-1243/cctbx_project/mmtbx/map_tools.py", line 55, in __init__ data = self.map_coeffs.data()*scale) Thanks in advance for any help Subhani

Re: [phenixbb] problems with Rosetta_mr
by Yoni - UW 22 Dec '12

22 Dec '12

Thank you For you suggestions, Tom! Unfortunately I already ran the phenix.regression.wizard a few time, and actually also for the rebuild module only. This module seems to cause me all the troubles. It goes to the wrong .map file (compared with the provided log files of the tutorial) and have trouble reading the edited alignment file. I also tried to use the .eff files to run the failed steps only, with similar results. Another thing i think is worth mentioning is that I have a suspicion something is wrong with my installation of Phenix, because when I try to run "autobuild.creat 20 very good models" from the GUI it fails with an autobuild error, while working well with the command line. Thanks again, Yoni

Excluding atoms from coordinate refinement ignored
by Engin Özkan 22 Dec '12

22 Dec '12

Hi Phenix developers, I have an issue using 1.8.1 (1168) with excluding atoms from coordinate refinement. I have defined a certain residue to be excluded from coordinate refinement, as can be seen in the .eff file produced by this run. refine { strategy = *individual_sites individual_sites_real_space rigid_body \ *individual_adp group_adp *tls *occupancies group_anomalous sites { individual = not (resseq 60 and resname PHE) torsion_angles = not (resseq 60 and resname PHE) rigid_body = None ... However, this gets ignored, and this residue and its NCS-related brethren get moved into nondescript electron density on a symmetry axis. This residue was just fine in an earlier version of Phenix, but when I switched to 1.8.1, it started moving into this density. So, I thought excluding it from xyz refinement, which is a dirty trick in my opinion, would fix this problem. Not so. I have the feeling that this is due to rotamer corrections as part of the torsion NCS implemented in 1.8.1 now. Sticking a zero occupancy dummy atom in the density did prevent this residue from moving in. Turning off torsion NCS also fixed it. By the way, I have "fix rotamer sidechains" off, as I am yet to see it improve things (at medium or low resolution). Thanks and happy holidays! Engin

Problems with rosetta_mr
by Yoni Haitin 21 Dec '12

21 Dec '12

Hello all, I have been trying (desperetly) to run the Rosetta_MR. I have encountered some problems with my data, so I switched to the "HNP3-mr-rosetta" tutorial dataset. I followd the debugging suggestions in the instructions webpage with no improvement. It seems that I have a problem in the rebuild stage. Attached are the RUN_FILE_1.log from REBUILD_IN_SETS_5 and ../WORK_1/rebuild.log. The edited_align.ali file cannot be opened for some reason. Another issue is that the map used is being taken from "overall_best_denmod_map_coeffs_nf.map" instead of "cycle_best" (as is in the tutorial's mr_rosetta_output log). this seems to produce an error (last log file attached). What should I do next?

problem about phase caculate
by yzhao 19 Dec '12

19 Dec '12

Hi everyone, I have came into a problem recently. My structure was solved by MAD and a crude model was built manually. Several peak data sets were collected, resolution is about 4A-4.2A. The heavy atom can be located by anomalous difference fourier. I feed the initial phase or heavy atom sites, and the peak data set to phenix. However the map after DM is too bad. The density is very strange. I don't know what's the problem? In addition, how to define protein mask at phenix autosol for density modification? Thanks in advance. -- Yan Zhao, M.Phil.
