CBMS Lecture Series - Vanden Zanden

23 Oct '25

You are cordially invited to join the Center for Biomolecular Structure Lecture Series ……….. Crystal Vander Zanden University of Colorado www.vanderzanden-lab.com<https://urldefense.com/v3/__http://www.vanderzanden-lab.com/__;!!P4SdNyxKAP…> WEDNESDAY, November 19, 13:30 (EST) "Assessing Membrane Protein Structures Using Liquid Surface X-ray Scattering” Register in advance for this meeting: https://bnl.zoomgov.com/meeting/register/2R2GbeNJTa-QtcoJRA7Vjw<https://urldefense.com/v3/__https://bnl.zoomgov.com/meeting/register/2R2Gbe…> Time conversion Link: https://www.worldtimebuddy.com/<https://urldefense.com/v3/__https:/gcc02.safelinks.protection.outlook.com/?…> Abstract: In the Vander Zanden lab, we use complementary liquid surface X-ray scattering and molecular dynamics methods to study the structure of protein/membrane interactions, particularly focusing on protein families that have dynamic behavior at membrane surfaces. Specifically, X-ray reflectivity and grazing incidence diffraction will be showcased as powerful tools for determining structural information about peripheral membrane proteins. We will discuss application of these techniques to study three protein/membrane systems: glycolipid recognition proteins, amyloidogenic proteins, and lipoxygenase enzymes. For each of these systems, a lipid monolayer is deposited at the air/water interface in a Langmuir trough, and proteins are injected into the liquid subphase below, where they can bind the membrane. These thin-film measurements are used to deduce an electron density profile describing the membrane and bound proteins. Diffraction data are used to detect semi-ordered species present at the membrane, such as protein assemblies and lipids organized into condensed domains. Overall, we feel these methods are a valuable addition to the classic suite of structural biology techniques, and their strength is the ability to capture a population of membrane proteins exhibiting dynamic behavior. ================= 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 ________________________________ To unsubscribe from the CCPEM list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/WA-JISC.exe?SUBED1=CCPEM&A=1<https://urldefense.com/v3/__https://www.jiscmail.ac.uk/cgi-bin/WA-JISC.exe?…>

Off-topic: Postdoc opportunity – Protein–protein interactions / Quantitative Interactomics
by Gergő Gógl 20 Oct '25

20 Oct '25

Dear colleagues, Sorry for the off-topic post, but I would like to share a *postdoctoral position* open in my team at the *Institut de Biologie Valrose (iBV)* in Nice, France. Our group investigates *motif-mediated protein–protein interactions* underlying key biological processes such as *cell signaling* and *cancer*, using *quantitative interactomics* and *biophysical approaches* (e.g. the *native holdup assay*). We are looking for a motivated researcher who has *recently defended their PhD*, with experience in *recombinant protein production and purification*. Expertise in *biochemistry*, *biophysics*, or *structural biology* would be highly relevant, and the position offers opportunities to apply these skills to proteome-wide interaction mapping. *Start date:* as early as December *Contract:* 6 months, with possible extension *Location:* iBV, Nice, France Full details of the call: https://euraxess.ec.europa.eu/jobs/381589 Best regards, *Gergo Gogl* Team *Quantitative Interactomics and Disease-Related Networks* *Institut de Biologie Valrose (iBV), Nice*

Zero B-factors
by p.auffinger＠unistra.fr 20 Oct '25

20 Oct '25

Hi, I have a large structure for which I just want to update B-factors. Unfortunately, I get zero values for some B-factors. Basically, I modified coordinates of a PDB deposited file and used the deposited cry-EM map. Is there something in the header (present or missing) that could influence the outcome of such a calculation ? Thanks, Pascal

Dear All, I am currently working on depositing a PDB file for an icosahedral virus and have built the pdb for one asymmetric unit (ASU). I am wondering how I can compile or obtain the BIOMT record. I haven't found a detailed protocol online. Thank you, Lei
