Selenium Nucleic Acids
by SeNA Research Institute 06 Sep '19

06 Sep '19

Dear Chemical and/or Structural Biologists, To serve our community, we have developed the selenium-atom specific derivatization of nucleic acids for crystallographic studies. We have discovered that virtually without any perturbations, the incorporated Se-atoms on nucleic acids can (I) rationally solve the phasing problem and (II) significantly facilitate nucleic acid crystallization (even with higher resolution and much larger crystals) in many cases, including protein-nucleic acid complexes. Currently, we are looking for collaborators and would be happy to offer free samples of Se-DNAs and Se-RNAs for your structure-and-function investigations. If you are interested, please contact us at SeNA(a)senaresearch.org Thanks, Mike SeNA Research Institute Email: SeNA(a)senaresearch.org Web: www.SeNAresearch.org http://www.senaresearch.org/

CCTBX documentation questionnaire
by Dorothee Liebschner 19 Aug '19

19 Aug '19

Hi everyone, During this year's ECM computing school, it came up that the CCTBX does not have a lot of documentation. This seems to be a major reason why people don't use it, even if they would like to employ the libraries. We would like to find out which parts of the CCTBX are the most interesting for users. We certainly cannot provide extensive documentation for the entire toolbox, but we can see what we can do once we know the main areas of interest. So if you were in the situation of wanting to use the CCTBX but decided to stay away from it because the documentation was non-existent or obscure, please let us know by filling out the questionnaire below (it's anonymous): questionnaire CCTBX documentation <https://forms.gle/9RawJFfHyEvhCVVP7> Best wishes, Dorothee -- Project Scientist, Molecular Biophysics and Integrated Bioimaging Lawrence Berkeley National Laboratory 1 Cyclotron Road, M/S 33R0345 Berkeley, CA 94720 Tel: (510) 486-5709 Fax: (510) 486-5909 Web: https://phenix-online.org

Clipper updates for C++11
by Billy Poon 12 Aug '19

12 Aug '19

Hi everyone, As part of making CCTBX-based software compile with C++11, it looks like we need to update our checkout of clipper to the latest version. http://www.ysbl.york.ac.uk/~cowtan/clipper/clipper.html As a side note, is this a feature that is widely used?

Ligand build in coot
by Pham, Hang 01 Aug '19

01 Aug '19

Hello, I have an alpha-lactose as ligand in my model. It is possible that the glucose ring of alpha-lactose is opened since I do not see the whole density of ring and there are an extend density after C2’ of the glucose molecule. Does anyone know how to cleave the covalent between O’ and C1’ to form linear glucose in coot or should I build a new ligand from beginning (beta-galactose cyclic forming beta-1-4 glycosidic linkage with a linear glucose) in coot ?

ISOLDE dev builds now available
by Tristan Croll 30 Jul '19

30 Jul '19

Hi all, Since the release of ISOLDE 1.0b3 I've begun releasing regular (weekly~fortnightly) development builds of ISOLDE. These are built against the ChimeraX daily build at the time of release - if you download a ChimeraX-daily build and install ISOLDE in the usual way via Tools/More Tools... this is what you'll get. In case you're worried, the dev and official 1.0b3 builds install into different directories, so it's quite straightforward to have both versions running independently on the same machine. The dev builds are *not* compatible with the ChimeraX 0.9 stable release. Some important changes since 1.0b3/ChimeraX 0.9: - the ChimeraX team have fixed some bugs affecting PDB and mmCIF I/O (primarily involving the handling of "imperfect" files) - fixed a bug causing the simulation to crash if the minimiser didn't converge in the first round - added status messages during simulation startup, and clear indications of when a simulation is running/paused - improved simulation startup time, and handling of custom ligands (preparing ligand definition files is a work in progress and will currently need you to do some work outside ISOLDE - feel free to contact me if you have an urgent case) Best regards, Tristan

cbf to sfrm
by Tim Gruene 28 Jul '19

28 Jul '19

Dear all, recently the conversion from CBF to SFRM frame format with APEX was discussed on the Bruker mailing list ("Synchrotron data with Bruker Software"), including a potential bug that parameters in the frames other than the first frame are not set correctly. The workaround to re-convert from SFRM to SFRM a second time did not help in my case. I therefore updated my program sfrmtools, available at https:// homepage.univie.ac.at/tim.gruene/research/programs/conv/sfrmtools/ With the option '-u',you can provide the first frame of the run, and via '-p' a parameter file that contains the critical parameters (see documentation at above URL) to update the header for all frames in this run. In case you have twinned data and want to benefit from SAINT, this should be possible with this feature. Both 64bit Linux binary and the source code are available. The program has no dependencies and should compile under any platform. I did not debug this new feature very thoroughly, but it worked for me so far. Any bug reports are welcome to this address tim.gruene(a)univie.ac.at I hope this is helpful for one or two users. I acknowledge the thorough documentation of XDS, of SAINT, and of the SFRM header format.

Unwanted LINK records
by Luca Pellegrini 27 Jul '19

27 Jul '19

Hello, Phenix.real_space_refine generates a few spurious covalent bonds between protein and ligand in my structure, which distort the local structure, and then adds the corresponding LINK records in the output file. Is there a way to avoid this? I am aware of the anti-link option previously mentioned in the phenixbb: http://www.phenix-online.org/pipermail/phenixbb/2018-January/023677.html, but I was wondering if there was another way of preventing this from happening. I am using Phenix 1.15.2-3472.

Symmetry of map vs Symmetry of model
by pramod kumar 26 Jul '19

26 Jul '19

Dear all, I have a query related to symmetry imposition and corresponding tweaking of model. If symmetry (say, C4) was imposed during the reconstruction of a 3D volume, does symmetry also need to be imposed when building the atomic model (say, in Phenix)? Or could this constrain be relaxed? Do we need to tweak the model in Coot for other chains or since it is build on symmetrical partners therefore should only be made in one chain and copied for all without any fitting?

Phenix real space refine problems
by Gyles Cozier 16 Jul '19

16 Jul '19

Good afternoon, I have been having issues with the last 3 versions of Phenix (1.14, 1.15 and 1.16) when the XYZ(real-space) option is selected, version 1.13 was the last one that doesn't have this problem for me. This seems to place too much weight on correcting rotamer 'outliers' at the expense of fitting to the density. The proteins that I work on have always had some residues that consistently are identified as rotamer outliers, but these latest versions 'correct' just about all of them (typically from 1% down to 0.1%). The resulting structures show clear movement of the sidechains out of what should be their density. Image 1 (after using 1.13) and 2 (after using 1.14, 1.15 or 1.16) show a really bad example where the Arg sidechain even gets broken apart to be moved into the stronger density of a neighbouring symmetry Gln. Image 3 (after using 1.13) and 4 (after using 1.14, 1.15 or 1.16) is a more subtle example, but although the residue is no longer a rotamer outlier after refinement using 1.16, it clearly does not fit the density as well as after using 1.13. These subtle changes are particularly worrying, as they could easily be missed when checking the structure after refinement. Other members of the group have also noticed this problem for different proteins. So currently I have a choice of either using version 1.13 (which with Onedep no longer accepting pdb files makes things a bit inconvenient as is nice to use the latest version for getting the mmcif and validation), or to use 1.16, but switch off the XYZ(real-space). Has anyone else noticed this happening? Found a solution to the problem? Thank you for any suggestions, Gyles Cozier.

Re: [phenixbb] High B factors
by Kay Diederichs 12 Jul '19

12 Jul '19

Dear Sozanne, I expect these data were collected at a synchrotron, and they are quite weak at 2.5A? (would be good to know CC1/2 in the high-resolution shell) If so, what you see is normal, and there's most likely nothing wrong with your data or model. I've seen Wilson and average B-factors higher than the ones you cite, for perfectly correct models and well-measured data. It is just a fact that your protein's atoms vibrate in the lattice, and the B factors are a way to measure how much. There is a mathematical relation between B-factors and strength of diffraction at high resolution; the higher the former, the lower the latter. best, Kay On 7/11/19 6:49 PM, phenixbb-request(a)phenix-online.org wrote: > Date: Thu, 11 Jul 2019 11:50:52 -0400 > From: ssolmaz <ssolmaz(a)binghamton.edu> > To: phenixbb(a)phenix-online.org > Subject: [phenixbb] High B factors > Message-ID: > <CAHYfRfKKMViLmaEuVr0aANGu6iaW6ofMAWSKHZ5JuCnOusFQ4w(a)mail.gmail.com> > Content-Type: text/plain; charset="utf-8" > > Dear all, > We recently determined a protein structure by molecular replacement and the > statistics are looking good, however, the average B-factor is unusually > high, and the Wilson B-factor is high too.

High B factors

Dear all, We recently determined a protein structure by molecular replacement and the statistics are looking good, however, the average B-factor is unusually high, and the Wilson B-factor is high too. A quick research on the subject suggested that high B-factors are acceptable as long as one has excluded and double-checked for other crystallographic problems.

exclude atoms/regions in real space refinement
by Filip Van Petegem 04 Jul '19

04 Jul '19

Dear Phenix users, I want to exclude particular regions of a protein model, docked into a cryo-EM map, from real-space refinement. I know this is possible for refinement in reciprocal space, but is this possible for refining a cryo-EM structure against a map? E.g. I want to totally exclude a region with known crystal structure, placed in an area of poor local resolution, from any form of refinement, but want to apply all other options (morphing, simulated annealing, adp, Global minimization) to the remainder of the structure. (I didn't see this option in https://www.phenix-online.org/documentation/reference/real_space_refine.html ) best regards, Filip -- Filip Van Petegem, PhD Professor, Dept. of Biochemistry and Molecular Biology The University of British Columbia 2350 Health Sciences Mall - Rm 2.356 Vancouver, V6T 1Z3 phone: +1 604 827 4267 email: filip.vanpetegem(a)gmail.com http://crg.ubc.ca/VanPetegem/

Dear Structural biology community, AUC2019<https://auc2019.uleth.ca/>, the 24th AUC Workshop and Symposium, will be held at the University of Canterbury, Christchurch (New Zealand) from 24-29 August 2019. 1) Registrations are now open and details can be found at this website: https://auc2019.uleth.ca/. Early Bird Registrations have been extended to the 15th July. 2) Beckman Coulter Life Sciences is generously offering one scholarship to a Graduate student and one to a Postdoctoral fellow to attend AUC2019 in Christchurch, New Zealand. Awardees will have their transportation (including airfare) and registration to the symposium and workshops covered (to a value of $1500USD). In addition, awardees will give a short talk in the symposium on their research. If you are interested, please submit the following to Ren Dobson (renwick.dobson(a)canterbury.ac.nz<mailto:[email protected]>) by the 18th July: i) a 400 word summary on how AUC has been used in your research, or alternatively, how you intend to use AUC during your research. (in pdf format) ii) A CV (in pdf format) iii) a scientific abstract for the talk. A template for the abstract is here: https://www.dropbox.com/s/sccrqoyp9wo7alm/NZ.AUC2019_AUC_SampleAbstract_for…. (submit in pdf format) Note, deadline for the Beckman Coulter Scholarships is the 18th July. The winners will be announced by the 31st July. 3) As the scientific program<https://auc2019.uleth.ca/symposium.php> for AUC2019 emerges, events will be uploaded to the website. We strongly encourage you to submit abstracts for talks and posters<https://auc2019.uleth.ca/abstracts.php>. 4) The format of the event is a 2-3 day workshop<https://auc2019.uleth.ca/workshops.php> offering parallel, hands-on training in experimental design and the latest AUC data analysis software from the world experts in this area followed by a 2 day research symposium on AUC and complementary approaches: methodological development, combination with orthogonal techniques (SAXS, SANS, SPR, MST, SEC-MALLS etc), application in biosciences and material sciences. 5) The meeting is also timed such that delegates can also attend the Biomolecular interactions and Engineering Symposium<https://www.queenstownresearchweek.org/bio-interactions/>, which is part of the Queenstown Molecular Biology Conference (this is in Queenstown, NZ), although note that this is a separate conference. 6) Lastly, The European Biophysics Journal has kindly agreed to run a special issue to celebrate the research presented at AUC2019. Therefore, we invite those who wish to extend their talks to a journal publication to consider contributing original research articles to this issue. Please indicate your interest for inclusion in this volume below. Deadline for registration of a contribution is August 30 2019. We look forward to welcoming you to Christchurch, New Zealand next Spring(-ish)!
