THAUMATIN AFTER A HIGH DOSE X-RAY "BURN"
Overview
Specific radiation damage can be used to solve macromolecular structures, using the radiation-damage-induced phasing (RIP) method. The method has, been investigated for six disulfide-containing test structures (elastase, insulin, lysozyme, ribonuclease A, trypsin and thaumatin) using data sets, that were collected on a third-generation synchrotron undulator beamline, with a highly attenuated beam. Each crystal was exposed to the, unattenuated X-ray beam between the collection of a 'before' and an, 'after' data set. The X-ray 'burn'-induced intensity differences ranged, from 5 to 15%, depending on the protein investigated. X-ray-susceptible, substructures were determined using the integrated direct and Patterson, methods in SHELXD. The best substructures were found by downscaling the, ... [(full description)]
