Announcement - NSLS-II Early-Science Workshop for NIH-funded beamlines
by Robert Sweet 08 Dec '14

08 Dec '14

Sent on behalf of the Workshop Organizing Committee The NIH-funded ABBIX structural biology beamlines at the NSLS-II are approaching completion, delivering two crystallography and one scattering beamline for biological sciences. The performance of these beamlines will present opportunities previously unattainable at synchrotron light sources, creating challenges for data collection and scientific discovery. The beamlines will provide a photon-beam flux density at least five orders of magnitude greater than that achievable at the NSLS, and orders of magnitude greater than that achievable today at any synchrotron light source. Participation in the first science undertaken at these beamlines represents a unique opportunity for scientists to help deliver on their potential. We are organizing a workshop at BNL, to occur on Jan. 28-29, 2015, to help define and develop further the priorities for the scientific commissioning of these beamlines and their entry into routine operation. Interested participants will be able to present and discuss their vision for the early science case for each beamline, thereby helping to shape the international scene for structural biology. Find workshop information at http://workshops.ps.bnl.gov/?w=ABBIXJan2015, including a draft agenda and an opportunity to register and submit an abstract.

neighbouring residues with symmetry
by Swanand Gore 08 Dec '14

08 Dec '14

Hi All, I am sure this has been asked and answered a lot of times... Is there a python script somewhere that reads a mmcif file and for any residue in it, returns a list of residues within a certain distance of it. And it returns any symmetry-related copies of residues too within that distance. Any pointer greatly appreciated. Thanks, Swanand -- Swanand Gore, wwPDB at PDBe-EMBL-EBI, Cambridge swanand(a)ebi.ac.uk ............. http://pdbe.org

adding hydrogens to custom peptide bonds
by Dale Kreitler 04 Dec '14

04 Dec '14

Hi All, I am trying to add riding hydrogens to a model that includes beta-3-homoglutamine (B3Q). The monomer is not in the ccp4 library but it is a PDB chemical component. So far I have used elbow to build and optimize my own version of the ligand using the atom naming convention for a beta-amino acid in the PDB (where CB is in the backbone adjacent to the amino group, so the backbone goes like C-CA-CB-N). I am using a TRANS cif link from the monomer library for the N(alpha-amino acid) to C(beta-amino acid), and I have defined my own cif link for the N(beta-amino acid) to C(alpha-amino acid). However when I run phenix.reduce I can't get hydrogens to appear on the peptide bonds between the beta-amino acid and adjacent alpha-amino acids (hydrogens appear every where else on the ligand and in the model). I realize the effect of two hydrogens on the model is inconsequential but I would like to figure out how I can get phenix.reduce to recognize the bonds to my "ligand" as standard peptide bonds and add hydrogens accordingly. Thanks, Dale -- Dale Kreitler Gellman Lab UW Madison, Department of Chemistry

restraints between molecules in adjacent asymmetric units.
by jens j birktoft 04 Dec '14

04 Dec '14

Hi Everybody. Are there ways to restrain non-covalent interactions between molecules in adjacent asymmetric units? I know the custom bond procedure works well for covalent bonds. However I also would like to add restraints for (1) bond angles, (2) torsion angles (less important) and (3) nucleotide base-pairing. I know that all of these can be generated via the custom bond syntax, but that is a rather tedious and time-consuming process. Perhaps there is a simpler way I know this issue has been raised before but am unaware of any new developments. Cheers Jens -- +++++++++++++++++++++++++++++++++++++++++++++++++++ Jens J.

Phenix.ensemble_refinment questions
by Joseph Brock 04 Dec '14

04 Dec '14

Dear Phenix community, I was hoping that some of you may be able to clarify some questions about Phenix.ensemble_refinement: 1. In the associated publication (Burnley et al. eLife 2012;), the ensemble refinement is validated by comparing the correlation of the ensemble generated map, with the map generated from the experimental phases for PDB entry 1YTT ("The overall correlation coefficient between the electron-density map from the ensemble model (obtained without experimental phases) and the experimentally phased electron-density map was 0.903, compared with 0.873 and 0.895 for the published and re-refined single structures. These seemingly small improvements in over- all quality indicators allow for significant local improvements."). I am confused how one computes an experimentally phased from structure factors deposited in the PDB that contain only anomalous intensities/amplitudes and not Hendrickson-Lattman coefficients. Is there a program within the phenix package that can do this? In addition, the phenix.ensemble_refinement keywords include: * experimental_phases * file_name = None * labels = None * Is it possible to include experimental phases during the rolling average refinement process and could this be beneficial (if the phases were of a sufficient quality)? 2. Is the correct procedure in parameter optimisation to optimise pTLS, then temperature offest and then tx? Or is it possible that the best ensemble may be generated from any (non-directional) combination of the above parameters? 3. What is the function of the "nproc" keyword? If this is the number of CPU cores that can be used in parallel, what is the most efficient way of using phenix.ensemble_refinement on a cluster? 4. Can anybody suggest a good way to compare the ensembles generated by phenix.ensemble_refinement with the trajectories of traditional MD simulations (for e.g. produced by NAMD? ;) Finally, I noticed that I cannot run phenix.ensemble_refinement using a "my_parameters.eff" file, it is necessary to type on the command line. Alternatively, the queueing system for the supercomputer I use is managed by SLURM, however, I cannot submit batch jobs via the appropriate command sbatch with anything other than default parameters (keywords in a parameters.eff or that are typed explicitly following the mycoords.pdb mydata.mtz myrestraints.cif files are not incorporated into the resulting parameters of the .log file). Could these issues be due to my local environment setup? I am running Phenix 1.9-1692 Platform: intel-linux-2.6-x86_64 redhat-e6.5. Sorry for the long email and many thanks in advance for you help!
