where is brute rotation output
by Ursula Schulze-Gahmen 18 Feb '13

18 Feb '13

Hi, Has anybody experience with the output from the brute rotation function. I ran this and it finished without complaints, but there are no output files ***.rlist or ***.sol in the directory. I cannot figure out why and how to continue now with the translation function. From the log file it seemed that there were peaks that could have been written out. Thanks for any help Ursula -- Ursula Schulze-Gahmen, Ph.D. Assistant Researcher UC Berkeley, QB3 356 Stanley Hall #3220 Berkeley, CA 94720-3220

Phaser problem for flexible domain of protein
by Appu kumar 18 Feb '13

18 Feb '13

Dear user, I have problem in finding the phase for the flexible DNA binding domain of LTTR protein. The unit cell parameters are ,Unit Cell: 46.92 105.30 47.75 90.00 103.26 90.00, and space-Group P 1 21 1. Molecular weight of protein is 36000Da. When i am running phaser it showing that Most probable MW of protein in asu for resolution = 49714.8. Could you please guide me how to set the proper setting for finding the correct rotation function and translation function setting to get the phases for the full length protein. I m getting the phases for the ligand binding domain but not for the DNA binding domain. Could you please suggest me some tricks which would work to get the phase. Thanks a lot in advance. Appu

Trouble with Phenix
by Rachel North 17 Feb '13

17 Feb '13

Hi, I have been having some issues with Phenix. When I input the mtz file (generated from CCP4), an error message appears... "File format error: cctbx Error: invalid combination of values while extracting anomalous array from columns: F New, SIGF New, DANO New, SIGDANO New, hkl= -3,25,44." This happens when I try to use the reflection file editor, xtriage and phenix refine. I have tested datasets collected from other crystals in the same condition and still have the same problem. I have also tried to process my data using different programs (XDSME and iMOSFLM) before going to CCP4 and then Phenix for refinement. I have never had this problem before and I have run every program on CCP4 the same way that I usually do. Does anyone know how I fix this or where I am going wrong? Kind Regards

how to make covelent link of BME with Cys and refine

Hello Nat, Thank you so much for your suggestion. I did run phenix refinement in nightly build phenix version with " intra_chain = True " command. This time refinement worked but again in out put pdb no disulfide bond is estabilished between cys and BME. I provided .pdb, .mtz and .cif files as input. Well can you please suggest me how i can provide both BME and Cys-BME (SS bond) restrains in .cif file? if that happens then i feel refinement should work.

HETATM automated chain assignment
by Talon Romain 15 Feb '13

15 Feb '13

Hello to the Phenix bulletin board community, I would like to know if I could find a tool to automatically assign HETATM atom (or even, water molecules) to the nearest protein chain ? In my case, I have 4 protein chains in the asymmetric unit : A, B, C and D. I would like to assign each ions and each ligands (which are numerous) with the chain letter of the nearest residue that coordinate them. Usually, I rename everything by hand but as the in-house program of the PDBe AutoDep deposition tool automatically do that... I beg your pardon if this question has just been posted here. I didn't find any tool either in the Phenix Suite or in the "Extensions" and "Calculate" menus of the Coot program (v0.7). Best regards. Romain Talon

Hello Sabine Yah i could specify link in the pdb and also could see it in coot but when i go for refinement then bond is broken. I given pdb mtz and cif files in refinement. The only problem i feel could be that i don't have restrains for SS bond in cif file but i don't know how to generate SS-bond restrains. Thanks RAJ

Re: [phenixbb] how to make covelent link of BME with Cys and refine
by Ed. Pozharski 13 Feb '13

Excellent point. The difference between using bme and cme is rather ideological. I would say that incorporating cme implies that your protein was somehow synthesized with non-canonical amino acid. Usind bme seems more in line with what actually happens - betamercaptoethanol forming disulfide bond with a cysteine. In practical sense, both things work. Until IUCr comes up with a convention, one is free to ignore ideological considerations :) -------- Original message -------- From: Abhinav Kumar <abhinavk(a)slac.stanford.edu> Date: To: phenixbb(a)phenix-online.org Subject: Re: [phenixbb] how to make covelent link of BME with Cys and refine How about using residue CME which is the CYS and BME linked together.

FW: phenixbb Digest, Vol 87, Issue 3
by Phoebe A. Rice 10 Feb '13

10 Feb '13

Hi, Although its theoretically possible, I've never had 5-Br-dU cause a problem. My approach would be to pick the strand with more T's and get every T replaced with 5-Br-dU, unless the 3' nt is a T (you pay a lot more for 3' modifications). We have had issues where crystals wouldn't grow with a heavily 5-I-dU modified DNA, presumably because Iodine is significantly bigger than a the 5-methyl of T, and it annoys the protein. If you've got good footprinting data, you may be able to guess where the protein will "care" about the surface of the major groove, and avoid putting iodines in those regions. If not, its probably faster to just order several oligos and try them all. If you've got a lot of T's and are worried about locating all those heavy atoms, I'd go for one derivative with a couple of paired 5-I-dU's (in spots where you have two T's in a row) in hopes that that will give you a toehold on solving the Patterson, and then a 2nd where every T on one strand is brominated, which may provide more phasing power. Note that both of these pop off in the x-ray beam, so collect your anomalous data first and fast. Also note that if you're lucky, you can get an extra large delta f' by subtracting the last data set from the first ("radiation induced phasing"). Hope that helps!

How to model domain-wide disorder in Phenix.refine (turn off bump interactions) ?
by Phil Jeffrey 08 Feb '13

08 Feb '13

Hi, I've got a pernicious problem where the electron density for one domain appears to extensively interpenetrate another similar domain. I'm in the process of trying to work out things like: MR solution in the wrong space group courtesy of pseudo-centering. In the meanwhile I want to model it as interpenetrating domains, and need to turn off VdeW bumps at the domain (chain) level of structure. I can't just model it as a infinite list of alternate locations. I (think) I remember how to do this in CNS (constraints interaction), but is there a way to do this in phenix ? I could not track down a particularly promising section of either the manual or the .def/eff file(s). Thanks Phil Jeffrey Princeton

Designing heavy atom positions on my DNA crystal
by Xiang Li 06 Feb '13

06 Feb '13

Hi everyone, I am trying to grow my DNA crystal with bromide derivatives. The content in one asymmetric unit is a 30 bp DNA duplex. I am considering about how many bromides modified bases should I use to ensurethe strong enough heavy atom signal. Also where to put these bromides? To my understanding, maybe I should put the heavy atoms at the most rigid places, avoiding the clashes and not too close to other heavy atoms. I have few experience on this and hope you could give me some help on the design. Thanks a lot! Sincerely, Xiang

Phaser annoyance
by Morten Groftehauge 05 Feb '13

05 Feb '13

Hi guys, The pop-up warning from Phaser about lack of eLLG for the resolution of the data would be more informative if you added the value of eLLG so one wouldn't have to scroll back in the log to find it. It would also allow the user to see with a glance whether the warning is because eLLG is under 120 or under 60. And it seems like the 'non-simple' Phaser GUI is broken in 1.8.2-1288. At least I haven't been able to open it, neither from the main window or by opening a previous job (Ubuntu 10.04). Cheers, Morten -- Morten K Grøftehauge, PhD Pohl Group Durham University

MR: Apply rotation and translation to structure factors
by Shweta Kailasan 01 Feb '13

01 Feb '13

Hello, I am trying to use a cryo-EM map as a MR model for an Xtal data set. I have calculated structure factors for my map using SFALL. And also used rotcross and trans.com (from AMORE) to determine best possible rotation and translation solutions. Is there is a program/script available that can be used to apply those rotations and translation to structure factors ? Most programs start with a coordinate file (pdb) as a model whereas my initial model is a map. I tried to use Phaser but it didnot work out. Any help would be highly appreciated. Thank you. -S <peter.ramsumair(a)credit-suisse.com>

Problem getting Phenix and Rosetta working together
by Dale Tronrud 31 Jan '13

31 Jan '13

Hi, I would like to get mr_rosetta running on my CentOS 6.3 64 bit computer but I can't seem to get them connected. I'm probably doing something stupid/silly but I'm stumped. I've downloaded, installed and compiled rosetta3.4 in the folder /usr/local/rosetta3.4. There are a bunch of files in rosetta_source/bin and they are executable. However, typing the following commands shows my problem. [dale@athena tln]$ echo $PHENIX_ROSETTA_PATH /usr/local/rosetta3.4 [dale@athena tln]$ ls -l $PHENIX_ROSETTA_PATH total 156 drwxr-xr-x. 10 root root 4096 Mar 20 2012 Antibody drwxr-xr-x. 3 root root 4096 Jul 26 2011 foldit-3.4 -rw-r--r--. 1 root root 1115 Mar 25 2012 new_apps.note drwxr-xr-x. 25 root root 4096 Mar 20 2012 protocol_capture -rw-r--r--. 1 root root 460 Mar 25 2012 README.Copyrights -rw-r--r--. 1 root root 12 Mar 25 2012 README.version -rw-r--r--. 1 root root 3345 Mar 25 2012 release.note drwxr-xr-x. 19 root root 106496 Mar 25 2012 rosetta3.4_user_guide drwxr-xr-x. 9 root root 4096 Mar 25 2012 rosetta_database drwxr-xr-x. 61 root root 4096 Mar 20 2012 rosetta_demos drwxr-xr-x. 11 root root 4096 Jan 30 15:27 rosetta_source drwxr-xr-x. 7 root root 4096 Mar 27 2012 rosetta_tests drwxr-xr-x. 13 root root 4096 Mar 20 2012 rosetta_tools [dale@athena tln]$ phenix_regression.wizards.test_command_line_rosetta_quick Skipping phenix rosetta tests: rosetta build not available. I can try "mr_rosetta" itself but it just tells me that I need to set PHENIX_ROSETTA_PATH. What, in particular, is Phenix looking for to determine that Rosetta is installed? Dale Tronrud

Seats are still available for RapiData - the deadline is in 4 days for our course on Data Collection and Structure Solving at the NSLS.
by Robert Sweet 31 Jan '13

31 Jan '13

We will present RapiData 2013, the fifteenth offering of our popular course: Rapid Data Collection and Structure Solving at the NSLS: A Practical Course in Macromolecular X-Ray Diffraction Measurement The course will be held 21-26 April 2013: http://www.bnl.gov/RapiData/. Students could be at any level from advanced undergraduate to full professor. The course should accommodate 48 students total. We encourage all students to bring their own specimens for data collection, and to bring old data for the data-reduction and structure-solving tutorials. Please read the Course Announcement at http://www.bnl.gov/RapiData/. You'll see that many experts in the field will be available for lectures and tutorials. You'll find the application materials on the Course Application tab at this site. For the eleventh time we will hold a short lecture course on the fundamentals of crystallography for roughly five hours on Sunday 21 April. The body of the RapiData course really requires that students have a healthy knowledge of crystallography. For potential students who have some experience but are shaky about fundamentals, this course will help. There will be a small additional fee for the fundamentals course, to pay for Saturday night accomodations and food on Sunday morning and noon. Latin American Scientists: Several scholarships are available, from the International Union of Crystallography, to pay partial travel and subsistence costs for Latin-American students and junior faculty (under 40 yrs). Please apply for the course, and then contact R. Sweet (sweet(a)bnl.gov) if you are interested in applying for a scholarship.
