On estimating Unitary Structure Factor distribution
by Andre LB Ambrosio 15 May '19

15 May '19

Dear all, We seek to calculate the distribution of Unitary Structure Factors, Uhkl, from a few datasets (at different maximum resolutions) for which the corresponding atomic models are already available at the PDB; this according to the formula (6.4), in the 2nd edition of Jan Drenth´s book: Uhkl = exp[B*(sin^2(theta)/lambda^2)] x FOBShkl / F(000) Hence, the following questions: - Is there any macromolecular crystallography software that can compute Uhkl as above, or equivalent? - If not, would it be more correct to use the Wilson-B or the mean B from the final model? - How can F(000) be best estimated from the final model, which is not necessarily always the most complete or best refined? Should we simply add together the number of electrons for all the atoms refined in the asymmetric unit (protein + ligands + solvent)? Many thanks in advance and best wishes, -- Andre LB Ambrosio

Postdoctoral Research Assistant at University of Dundee (Alessio Ciulli)
by KH Chan 15 May '19

15 May '19

Posting on behalf of Prof. Alessio Ciulli: Professor Alessio Ciulli’s laboratory is seeking a postdoctoral researcher to undertake research in collaboration with one of the leading pharmaceutical companies supporting the Division of Signal Transduction Therapy (DSTT). The DSTT facilitates collaborations between some of the world’s major pharmaceutical companies (Boehringer Ingelheim, GlaxoSmithKline, and Merck-Serono) and leading Dundee-based researchers with a proven track record of achievement in understanding and exploiting the fundamental molecular causes of human disease in the fields of cancer, immune-regulation, neurodegeneration and hypertension resulting from disruptions in protein ubiquitylation, phosphorylation and other signalling networks. The successful applicant will be based within the Ciulli lab in Dundee ( http://www.lifesci.dundee.ac.uk/groups/alessio-ciulli). The laboratory is pioneering novel chemical structural biology approaches to target E3 ubiquitin ligases with small molecules. The applicant will employ state of the art structural biology, cell biology and biophysical approaches to conduct molecular and structural studies on disease-relevant human E3 ubiquitin ligases. The Ciulli lab has close collaborations and access to facilities available within both the MRC Protein Phosphorylation Unit ( http://www.ppu.mrc.ac.uk/) and more widely within the School of Life Sciences. This set-up will ensure the successful candidate will have access to whatever technologies required to conduct the projects that they are working on, including molecular, biochemical, mass spec proteomics, pharmacological and genetic methodologies including CRISPR/CAS9 knock-out and knock-in technologies. There will be regular opportunity for interaction and to discuss data within the group and with the collaborating pharma company. Candidate requirements: ‧ PhD with outstanding academic track record and at least one first authored publication in an internationally recognised peer-reviewed journal. ‧ Strong background in Biochemistry, Molecular Cell Biology, or Structural Biology is required. ‧ Strong interest in signal transduction research and how disruptions of these pathways are linked to human disease is expected. ‧ Experience with recombinant protein expression and purification, molecular cloning, and protein X-ray crystallography (or cryo-EM) is required. ‧ Experience with mammalian cells tissue culture, and protein-protein interaction studies inside cells e.g. pull-down, proteomics, would be highly advantageous. ‧ Experience with biophysical methods to study in vitro protein-protein and protein-peptide interactions is desirable. ‧ Capable of working in a team, but able to plan and work independently. ‧ Excellent communication skills and knowledge of the English language are essential. ‧ The candidate should have ambitions to become a successful independent researcher either in academia or the pharmaceutical/biotechnology industry. The fund for this project is available till 30th June 2020 in the first instance with a chance to renew.

Research Associate (Fixed Term) at the MRC Mitochondrial Biology Unit, University of Cambridge
by Jonathan Ruprecht 15 May '19

15 May '19

Posting on behalf of Dr Edmund Kunji: The University of Cambridge wishes to appoint a Postdoctoral scientist to join the research group of Dr Edmund Kunji in the MRC Mitochondrial Biology Unit of the University of Cambridge. The postholder will work within a programme focussed on mitochondrial transporters. Transport processes are crucial for the functioning of mitochondria and mutations in transport proteins cause of a wide range of metabolic, neuromuscular and developmental diseases. Basic molecular understanding of their structure and mechanism is required to understand their role in health and disease. The goal of the project is to study their structures in different conformational states by electron cryo-microscopy and/or x-ray crystallography. The post-holder will participate in every stage of the process, from the generation of expression strains or cell lines, isolation of mitochondria, purification and sample preparation, data acquisition and processing, and structure model building and interpretation. There will also be an opportunity to study their role and mechanism using a wide range of biochemical and biophysical techniques. This project is part of a collaborative SNF Sinergia grant together with Profs. Hediger and Lochner of the University of Bern. Candidates will have a PhD in Structural Biology/Biophysics or related disciplines, and a track record of research achievements. Knowledge of protein purification and experience in structural biology are essential. Further details about the job may be found here: http://www.jobs.cam.ac.uk/job/21519/ The MRC Mitochondrial Biology Unit is a world-renowned centre for mitochondrial research. Additional information can be found at www.mrc-mbu.cam.ac.uk. Fixed-term: The funds for this post are available for 3 years in the first instance. The closing date for applications is Wednesday 12th June 2019 with interview date yet to be confirmed. Informal enquiries may be made to Dr Edmund Kunji (ek(a)mrc-mbu.cam.ac.uk).

Cutting out a fragment from cryoEM map
by Sunandan Mukherjee 14 May '19

14 May '19

Hi, I want to build an RNA model using cryo-EM density. The structure is of a protein-RNA complex and the map consists regions with protein subunits. Is it possible to separate the portion of the map which represents the RNA only? Thanks and regards, Sunandan -- Sunandan Mukherjee (PhD) Research Assistant Laboratory of Bioinformatics and Protein Engineering International Institute of Molecular and Cell Biology (IIMCB) ul. Ks.

Dear Phenix bb, I am facing a problem when trying to instal Rosetta locally. I have installed Rosetta 3.9, set a local environment to my c-shell (setenv PHENIX_ROSETTA_PATH "/Applications/rosetta_src_3.10_bundle") and compiled with ./scons.py -j4 mode=release bin in main/source/ folder. When I try to run rosetta.run_test I get the following error:"OSError: [Errno 2] No such file or directory: '/Applications/rosetta_src_3.10_bundle/main/source/bin' " though the folder is there. Could you please help me?

Rosetta cannot Rebuild
by Perry, Kay H. 09 May '19

09 May '19

I am having a problem with mr_rosetta where I cannot make it past the rebuild step. I have made fragment files using the old Robetta Server and I am using a hhpred alignment file, but even if I try with a model_already_placed when I reach rebuilding, I get the following error. protocols.looprelax: === protocols.looprelax: === Remodel protocols.looprelax: === ERROR: frag_libs().size() > 0 ERROR:: Exit from: src/protocols/comparative_modeling/LoopRelaxMover.cc line: 47 7 My PHENIX_ROSETTA_PATH is pointed at /share/apps/necat/programs/rosetta3.4 so I believe I am using version 3.4 of rosetta.
