I had the same problem with an even higher %identity once (>80%), eventually resorted to SIRAS phasing with a mercury compound, and I found a case of domain swapping creating a novel dimer interface. Flip

Hi Somu, Here are a few questions which might help: Are you sure about about your space group? Is another lattice/symmetry possible? Is twinning possible? Have you tried all possible space groups in MR? Have you tried different resolution ranges (e.g. all data, cut low resolution at 15 A, cut hi

I struck with MR problem. MY target has 76% sequence identity with the model. I tried Phaser, AMoRe and Molrep. None of them gave me satisfactory solution. If you have any suggestions and or New programs I would like to try. that is odd. at 76% SI mol. repl. should normally be a breeze. possib
