Dynamic Structures in DNA Damage Responses and Cancer in Cancun, Mexico

Young researchers are encouraged to apply for the Cancun conference “Dynamic Structures in DNA Damage Responses and Cancer” from the 12-15th February, 2014. We expect that there will be lively discussions on both methods and results during the sessions and good opportunities to interact with top colleagues. To inspire your productive discussions the conference venue…

Nanogold labels used to characterize DNA bending in mismatch repair

Greg Hura and colleagues developed and applied nanogold labels for DNA complexes with proteins examined by small angle X-ray scattering (SAXS) to follow DNA conformations acting in error detection by the mismatch repair (MMR) system in solution. This technique can examine short or long pieces of DNA and in most solution conditions, including those closest…

New crystal structures of translocating ribosome

Several new crystal structures of the 70S ribosome in complex with EFG and non-hydrolyzable GTP analogs have revealed how the ribosome directionally translocates mRNA and the tRNAs through the A, P, and E sites and how specific features of EFG and ribosomal RNA act as pawls to enforce this ratcheting mechanism. The new structures were…

Reflections on a career studying ribosomes

>*We spent many long nights at the Advanced Light Source, running on coffee, donuts and barbecued ribs from the legendary Everett & Jones BBQ in West Berkeley.* A very interesting historical reflection by Harry Noller entitled “By Ribosome Possessed” has just been published in JBC. It is his personal account of growing up in the…

Comprehensive macromolecular conformations mapped by quantitative SAXS analyses

SIBYLS scientists have recently published and made available tools for generating [SAXS structural comparison maps](/saxs_similarity “SAXS structural comparison maps”). Details of the methods have been published in Nature Methods. >Biological macromolecular functions require distinct conformational states that are challenging to examine comprehensively. Current methods to quantify conformational similarities and distinguish different assembly states are underdeveloped.…

Super-Resolution in Solution X-Ray Scattering and Its Applications to Structural Systems Biology

Rob and John have a new review on SAXS and its application to systems biology published in the Annual Review of Biophysics. See if you can spot the musical theme. >Small-angle X-ray scattering (SAXS) is a robust technique for the comprehensive structural characterizations of biological macromolecular complexes in solution. Here, we present a coherent synthesis…
