No working nightlies since 1.8.4-1496?
by Ben Eisenbraun 23 Oct '13

23 Oct '13

Hi All, I don't see any nightlies listed since then, and trolling the build pages, it looks like things are in a state of flux right now with quite a few broken builds. I don't actually care about the nightlies per se; I have a user that wants to try PHENIX with Rosetta refinement, and per an older thread, we need a Rosetta nightly release for that to work. Do we also need a PHENIX nightly? Or should 1.8.4 work for this purpose? Thanks. -ben -- | Ben Eisenbraun | SBGrid Consortium | http://sbgrid.org | | Harvard Medical School | http://hms.harvard.edu |

Postdoctoral Position in Protein Biochemistry / X-ray Crystallography (funded by Cancer Research UK) at ICR
by Sebastian Guettler 22 Oct '13

22 Oct '13

Dear PHENIX Community, We are currently looking for a postdoctoral fellow to join our research programme on the regulation and functions of ADP-ribosyltransferases. Please see the job description for the position and instructions on how to apply below. Best wishes, Sebastian Post-doctoral Training Fellow: Protein Biochemistry / X-ray Crystallography (funded by Cancer Research UK) We seek to appoint a Post-doctoral Training Fellow to a new team led by Dr Sebastian Guettler in the Divisions of Structural and Cancer Biology. The post is funded by Cancer Research UK. The successful applicant will undertake biochemical, crystallographic and functional studies on members of the ADP-ribosyltransferase (or “PARP”) family of proteins and their regulators. Our goal is to gain insight into the control and cellular roles of these enzymes with a specific interest in ADP-ribosyltransferase-dependent signalling processes linked to cancer. Applicants should possess a PhD (or equivalent) in biochemistry or molecular biology. Experience with recombinant DNA techniques, high-quality protein expression and purification, protein characterisation (such as protein-protein interaction analyses and enzymology) as well as protein crystallography is essential. Experience in protein production in insect cells would be of advantage. Appointment will be on a Fixed Term Contract for 3 years in the first instance, with a starting salary in the range of £28,425 to £34,944 p.a. inclusive (based on previous post-doctoral experience). For further details and instructions on how to apply, please refer to our online vacancy and recruitment site at http://www.icr.ac.uk/jobsearch, quoting job reference number 1376940 for this position. Closing date: 22nd November 2013 While applications need to be placed via our online system, informal inquiries can be sent to Dr Sebastian Guettler at sebastian.guettler(a)icr.ac.uk<mailto:[email protected]>. Research in the Divisions of Structural and Cancer Biology focuses on the functional, biochemical, and structural characterisation of cellular processes relevant to cancer and cancer therapy. The Division of Structural Biology has managed facilities for protein crystallography (crystallisation robots, Bruker Microstar and CCD detector), cryo-electron microscopy (FEI Tecnai F20 and T12), and protein production with expertise in multi-subunit expression (insect cell, yeast and bacterial expression, including a 60-litre fermentor). The Division is also well equipped with instrumentation for biophysical analysis (e.g. ITC, fluorescence, multi-angle light scattering). The Division of Cancer Biology provides a state-of-the-art infrastructure for mammalian cell culture, imaging, mammalian genetics, chemical biology and proteomics. The Institute of Cancer Research (ICR) is one of the world’s most influential cancer research institutes. Our mission is to make the discoveries that defeat cancer. We have a long and distinguished history of research with a major impact on the outcome for cancer patients. Our unique partnership with The Royal Marsden NHS Foundation Trust (RMH) makes us the largest comprehensive cancer centre in Europe, performing high quality original basic research and translational studies. Under the leadership of Chief Executive Professor Alan Ashworth FRS, we are committed to attracting, developing and retaining the best minds in the world. The ICR was ranked as the UK’s top academic research centre in the 2008 Higher Education Funding Council Research Assessment Exercise. Based on our publication record, citations and impact we rank among the world’s leading cancer research centres.

anisotropic refinement based on B values
by Yarrow Madrona 20 Oct '13

20 Oct '13

I'm sure that this has probably already been covered but I am having some problem finding out how to tell phenix to make a decision whether to refine isotropically or anisotropically based on B factor values. Is this something you can do with a python script? Thanks. -Yarrow -- Yarrow Madrona Graduate Student Molecular Biology and Biochemistry Dept.

increasing NCS restraints
by Yarrow Madrona 17 Oct '13

17 Oct '13

I am doing restrained NCS refinement and would like to know how to set the target weight of the cartesian restraint in the command line? I also found a sigma value in the GUI. I read that I can decrease it in order to increase the NCS restraints. However, I have seen this under Torsional restraints. Does this also apply to cartesian restraints? I am doing this so that I can look at the differences in position and B-factors of two molecules in the ASU that I am trying to determine are related by a perfect or imperfect 2(1) screw axis. (I posted a question about this on the CCP4 bullitan board.) If the values between molecules are exactly the same then presumably the space group is actually P212121 with 1molecule in the asu instead of P21 with two molecules. I already know that the P21 dimer superimposes almost exactly on the P212121 monomer and it's symmetry mate. I just don't know how "perfectly" they align and I am hoping this approach will tell me. I hope this makes some sense. -Yarrow -- Yarrow Madrona Graduate Student Molecular Biology and Biochemistry Dept. University of California, Irvine Natural Sciences I, Rm 2403 Irvine, CA 92697

Re: [phenixbb] Need help with atom selection for anisotropic refinement
by Nathaniel Echols 16 Oct '13

16 Oct '13

I think the problem is with the boolean logic ("and"/"or"). First, the isotropic: optional (element H or element D or resname HOH or chain E or chain F or > chain A or chain B) > This will be processed okay but it's going to select all atoms in chains A/B/E/F in addition to all H/D and waters, which probably isn't what you really want since the anisotropic selection includes chains A and B. I'm not sure what will actually happen here, but it's better not to rely on the atom selections being processed in a particular order (and better not to rely on the code automatically handling the problem of overlapping selections). chain A and chain B and not (element H or element D or resname HOH or chain > E or chain F or chain A resseq 5:11 or chain A resseq 66:72 or chain A > resseq 117:138 or chain A resseq 152:184 or chain A resseq 196:210 or chain > A resseq 249:251 or chain B resseq 3:6 or chain B resseq 66:72 or chain B > resseq 166:210 or chain B resseq 249:251) > The problem here is that you have specified that the atoms match "chain A and chain B", which is impossible. You probably want this: (chain A or chain B) and not (....) -Nat
