Hi Melissa, we need to have a closer look to understand what's happening... Could you please send us these PDB file: - original (before modifications); - file after modifications; - file after refinement; - cif file.

Modified DNA residue
by Melissa Ford 11 Jan '17

11 Jan '17

I'm having working on modeling a sulfur on the phosphate backbone of DNA in replace of one of the oxygens and have encountered some restraint problems. I've successfully managed to replace the oxygen with a sulfur in the proper geometry in a pdb, generate a cif file for the modified residue (adenosine 5'-phosphorothioate), and run an initial refinement. Upon that refinement, a few errors occur. First, since the phosphate bound to the sulfur is the first atom of the modified residue the angle between the O3' (of the neighboring residue) - P- S is not recognized and forced into an unfavorable geometry. When trying to add that additional angle to the cif file, I get an error. Aditionally, the change causes Phenix to not recognize the chirality of the C3' that the phosphate is bonded to and forces the ribose into a planar conformation. I am sure there is something I am missing that allows phenix to recognize this new residue as a modified nucleotide so that it knows these restraints. Any insight on this would be great. Thank you!

Multiple positions in Buffalo NY
by Edward Snell 05 Jan '17

05 Jan '17

Dear All, Just a reminder for those that may have missed it over the holidays. We have multiple positions for structural biologists in Buffalo NY. Please let anyone who may have an interest know of these opportunities. The first is with the Hauptman-Woodward Medical Research Institute: The Hauptman-Woodward Medical Research Institute (hwi.buffalo.edu) operates the High-Throughput Crystallization Screening Center providing crystallization and characterization services to the community at very competitive cost (www.getacrystal.org). A Ph.D. level research scientist position (post-doctoral or junior researcher) is available within the Center to guide operations on a daily basis, move research capabilities into production, and to help set the direction of the Center for the future. There is strong potential for both scientific growth and growth of responsibility. The candidate would be expected to have demonstrated expertise and productive research in the area along with appropriate publications. In addition to crystallization knowledge, experience with structural biology techniques in general is desired. Computational experience is a plus. The candidate should gave excellent communication, reading, writing, and presentation skills. They should be able to be a representative of the Center in the scientific community. They should have a good interpersonal skill set and be able to work with a diverse group. Evidence of seeking their own research funding would be viewed as a strong positive and the position would encourage the development of capabilities through active research efforts and collaboration. The Center interacts with both academia and industry and provides some crystallization screening services for a growing Gene to Structure company, HarkerBIO, (www. harkerbio.com). Collaborative possibilities are possible in this area. Research facilities at the Center include liquid handling robots, in-house developed plate imaging capabilities, SONICC and UV analysis, and X-ray analysis. The Center is well connected to several synchrotron facilities. A sophisticated computational infrastructure is in place. In both the X-ray and computational side, research advances are ready to be implemented into the Centers capabilities. The Hauptman-Woodward Medical Research Institute is 60 years old and based in Buffalo New York. It is at the center of a rapidly expanding medical campus. Good benefits are provided and the cost of living in the area is very competitive. For those with a focused research interest, the Institute is located adjacent to high-end computer facilities, a Comprehensive Cancer Center, a new Medical School under construction, and multiple biotech startup companies. Collaborative efforts with academic and industrial collaborators are strongly encouraged and aided by an umbrella organization on the campus. The Hauptman-Woodward Medical Research Institute, Inc. as an equal opportunity employer, extends employment opportunities to qualified applicants and employees on a non-discriminatory basis without regard to race, color, sex, creed, age, religion, national origin, marital status, veteran status, sexual orientation, genetic predisposition, carrier status, or disability that would prevent the performance of the essential requirements of the job with or without a reasonable accommodation in compliance with the appropriate New York State and Federal laws, or any other legally protected characteristics. This policy applies to all conditions and terms of employment. Formal applications should send a cover letter and resume along with three contacts for references to opportunity(a)hwi.buffalo.edu. The position is available in the New Year and will be open until filled. And on behalf of Artem Evdokimov, HarkerBIO CEO, the other positions are with a company called HarkerBIO housed in the Hauptman-Woodward Medical Research Institute building: HarkerBIO is hiring two *Research Scientist - Structural Biology * positions. Desired qualifications are quite broad, but can be summarized as follows: 1) someone who is a start-up enthusiast, not afraid of a challenge and has both the desire to innovate in science and the ability to do so. A PhD in related area is a plus, however we would consider qualified M.Sc. candidates. 2) someone with a relevant experience in at least 70% of the gene to structure 'process' - in other terms, the candidate is able to perform literature research, design clones, clone, express, purify, crystallize and solve structures -- or at least a good chunk of the above. Ideally someone with experience in mammalian and/or insect cell expression, and/or membrane protein work. 3) a scientist with a reasonably rounded skill set in biophysical characterization of macromolecules (SPR, DSF, anSEC/MALS, and so forth) 4) deep interest in developing structure-related technologies (e.g. expression systems, crystallization research, etc.). Desire and ability to participate in internal research projects. 5) high work ethic, impeccable documentation abilities, sense of humor 6) committed to relocating to Buffalo, NY HarkerBIO offer: Competitive salary (commensurate with experience) and full benefits Energetic and friendly work environment Coverage of reasonable relocation expenses for highly qualified candidates Co-location with a nonprofit research institute (HWI) and participation in the thriving research community at the Buffalo-Niagara Medical Campus HarkerBIO is an EO/AA employer. Please direct your inquiries to careers(a)harkerbio.com<mailto:[email protected]>. Note that for both positions, applications should be addressed to the emails given in the position descriptions. Happy New Year, Eddie Edward Snell Ph.D. President and CEO Hauptman-Woodward Medical Research Institute Assistant Prof. Department of Structural Biology, University at Buffalo 700 Ellicott Street, Buffalo, NY 14203-1102 hwi.buffalo.edu Phone: (716) 898 8631 Fax: (716) 898 8660 Skype: eddie.snell Email: esnell(a)hwi.buffalo.edu [cid:[email protected]] Heisenberg was probably here!
