Searching for a PhD position

Dear PhenixBB readers, I am searching for a PhD position in a lab that uses structural biology techniques (predominantly crystallography and electron cryomicroscopy) to investigate protein biochemistry, structure, catalysis and synthesis. I would also be interested in labs that conduct various structural studies on viral and bacterial(archaea) proteins. My goal is to conduct fundamental interdisciplinary research using structural biology as my main field of study. Brief CV: - Postgraduate in Cancer Cell and Molecular Biology from University of Leicester. - Extensive research experience in biophysical techniques with hands-on training in crystallography, Powder XRD, FT/IR and spectrophotometry. - Previous experience in studying Ascorbate Peroxidase (Haem peroxidase) biochemistry. - Very well trained in molecular biology, protein expression and purification. I am an international student not belonging to the UK/EU-region and would prefer a position that is fully funded. The location of the lab is not a constraint and, I would be glad to contribute to any lab that is conducting exciting research in the field of structural biology. I would like to thank all the readers for their time and consideration. Best wishes, Mohak Udiniya

CBMS Lecture Series - Padua - 22 July 2026

You are cordially invited to join the Center for Biomolecular Structure Lecture Series ……….. Ricardo Padua Howard Hughes Medical Institute The Scripps Research Institute WEDNESDAY, July 22, 13:30 (EDT) "Visualizing enzyme catalysis through X-ray crystallography" Register in advance for this meeting: https://bnl.zoomgov.com/meeting/register/sQhXauTtSGa3iwB6X-tQ3g Time conversion Link: https://www.worldtimebuddy.com/<https://urldefense.com/v3/__https:/gcc02.safelinks.protection.outlook.com/?…> Abstract: Understanding how protein motions contribute to enzyme function remains a central challenge in molecular biology. How are motions occurring on different timescales connected, and how do they contribute to catalytic efficiency? Have proteins evolved to preferentially access the conformational substates required for function? Recent advances in structural biology, protein engineering, and X-ray crystallography are providing new insights into these questions. Studies of directed evolution have revealed how enzyme dynamics can be optimized to produce highly efficient artificial catalysts, while developments in crystallographic data collection have enabled visualization of the molecular mechanisms underlying temperature adaptation in exceptionally proficient enzymes. Together, these findings highlight the intimate relationship between protein motions, evolution, and enzymatic function. =================================== Vivian Stojanoff, PhD Education, Training, Outreach User Program p 1(631) 344 8375 e lifescience(a)bnl.gov<mailto:[email protected]> w https://www.bnl.gov/ps/lifesciences/<https://www.bnl.gov/ps/lsbr/> Address: Center for Biomolecular Structure National Synchrotron Light Source II Building 745 Brookhaven National Laboratory Upton NY 11973

PDB deposition question: processed data in P6₃22, refined model in P6₃
by fbetulertem＠gmail.com 14 Jul '26

14 Jul '26

Hello everyone,   I have a question regarding PDB deposition.   The processed diffraction data are in P6₃22, while the refined structure is in P6₃. During PDB deposition, the validation server reports a completeness of only ~51% which appears to result from the difference in symmetry between the processed data and the refined model.   Would it be acceptable to deposit the structure in this situation, or should the diffraction data be reprocessed in P6₃ and refined again before deposition?   Thank you very much for your advice! Best, Betul
