WebbPerspectives: Enhancing X-ray Vision. Dorothy Hodgkin, one of the main founders of protein crystallography, possessed a unique mixture of skills that allowed her to extend the use of X-rays to reveal the structures of compounds that were far more complex than anything attempted before. Victory in Europe Day in Oxford, 8 May 1945. WebbTo further investigate this consensus motif, we determined the crystal structures of SPSB1, SPSB2, and SPSB4, as well as their binding modes and affinities for both Par-4 and VASA. Mutation of each of the three Asn residues in Par-4 abrogated binding to all three SPSB proteins, while changing EL to DI enhanced binding.
