Re: [phenixbb] C-beta outliers - it is 1.20 version issue
by Andrea Smith 14 Jul '24

14 Jul '24

Thank you everyone for suggestions. As it turns out, there is a problem in the 1.20 phenix version that I was using. I updated to 1.21 as suggested by Dorothee, repeated one refinement job and had no more C-beta outliers, so I am guessing I will not have them in other models either.

Why is this? Is there a way to tell phenix.refine not to move a specific amino acid during refinement?

refine and Table 1
by Andrea Smith 09 Jul '24

09 Jul '24

Hi everyone, * I have an issue with phenix.refine being unable to open generated pdb and mtz files in coot after refinement. It claims “ERROR: refinement output file not found!” This started happening after I opened the model in ChimeraX and used dssp command and then saved model as pdb that I used for further refinements. The files generated from phenix.refine actually exist, but instead of just being named e.g. myprotein_refine20.pdb they are called myprotein_refine19_refine020.pdb (yes there is an extra refine and an extra 0). This has never happened to me before. * I am also trying to generate "Table 1" for journal. I input my pdb into model file and mtz into reflection file. When I click Run, I get an error message: "a model is referenced in the phil which is not in the data manager". What does this mean? * I also tried to validate my model using pdb validate server, but when I upload cif files generated as output from phenix.refine, the server shows “Error processing uploaded files…Click to reload”. (However, when I use the Get PDB validation report task in phenix, I get a validation report pdf with no issues.) Is all of this caused by the changes the ChimeraX's dssp command did to my pdb? Thank you, Andrea Running Phenix 1.21-5207 from GUI on Ubuntu 20.04.3.

real_space_refine is un-glycosylating my protein
by robert＠oeffner.net 01 Jul '24

01 Jul '24

Hi, I am trying to do a refinement with phenix.real_space_refine (RSR) on an EM map with a protein and a known ligand (NAG is the monomer code). In the pdb file supplied the C1 atom in the NAG molecule is positioned nicely in the EM density at a distance of 1.38Å from a ND2 atom in an ASN residue of the protein. The O1 atom in the NAG molecule is not present suggesting there should be a covalent bond here I believe. Both ASN and the NAG molecule have the same chainID. The problem is that RSR moves the sugar away even though I have used command line options such as pdb_interpretation.automatic_linking.link_carbohydrates=True or even pdb_interpretation.automatic_linking.link_all=True. The atoms end up at an un-bonded distance of 2.85Å from each other after refinement to the point that one of them is poking out of the density. Are my phil parameters incorrect? I noticed that I don't get an error message if I misspell say pdb_interpretation.automatic_linking.link_carbohydrates to pdb_interpretation.automatic_linking.link_carbohydrate. RSR still runs to completion so I'm wondering if it actually interprets the PHIL parameter at all. Another peculiarity is that the log file comments that NAG is an unusual residue rather than stating it is a well-known carbohydrate. If anyone on here knows how to compel phenix RSR into creating automatic links to carbohydrates suggestions would be much appreciated. Many thanks, Rob

Extra map coefficients in 1.21.1-5286
by Dr. Kevin M Jude 30 Jun '24

30 Jun '24

In my latest installed version of phenix, I find that additional, redundant map coefficients are being added to the output mtz file. I compare an identical refinement originally run in 1.21rc1_5058 and then repeated in 1.21.1-5286. *_filled and *_4 appear to be redundant, and the final sets of coefficients (*_no_fill and *_5), appear to include the test set reflections, even though I’ve selected Exclude R-free set from map coefficients in the gui. This is a little bit confusing, but primarily an annoyance because auto-open mtz in coot can’t figure out which coefficients to use. 1.21rc1_5058 Col Sort Min Max Num % Mean Mean Resolution Type Column num order Missing complete abs.

Postdoctoral Job Position in Infectious disease and Small Angle X-ray Scattering
by Susan Tsutakawa 27 Jun '24

27 Jun '24

Dear fellow structural biologists, I would appreciate it if you could forward this message to any graduate students that might be interested. We have an opening for a Postdoctoral Fellow to use small angle X-ray scattering (SAXS) on global health problems and biopreparedness in response to infectious disease work at the SIBYLS <http://bl1231.als.lbl.gov/> Beamline in the Advanced Light Source Synchrotron (ALS) at Lawrence Berkeley National Laboratory (LBNL) In this exciting role, you will work with a multi-disciplinary team of scientists as part of the ArpaH program <https://arpa-h.gov/>, structurally characterizing purified proteins from pandemic-potential organisms and relevant antibodies. The primary technique used will be Small Angle X-ray Scattering, which provides distance information that can reflect protein conformations and complexes in solution. You will work with a team to develop portable instrumentation to enable high throughput SAXS sample handling that can work at other synchrotrons. Through this work, you will develop ties to other national laboratories and within Berkeley Lab, specifically within the National Energy Research Scientific Computing Center (NERSC <https://www.nersc.gov/>), a division within the Computing Sciences Area’s <https://cs.lbl.gov/>. Prior experience in structural biology, protein biochemistry, and basic programming would be advantageous. Experience in SAXS is not a requirement. For more details. please see https://lbl.taleo.net/careersection/2/jobdetail.ftl?job=102111 This position has an anticipated start date of September 1, 2024. LBNL is located in the San Francisco Area in Berkeley, CA. Sincerely, Susan Tsutakawa Head of Structural Biology Molecular Biophysics and Integrated Bioimaging Biosciences Area Lawrence Berkeley National Laboratory.
