MR solution of the MTH685 protein crystal structure. (a) The one-by-one MR protocol in which the RF is computed only once for each single-domain search model. (b) The MR protocol with two feedbacks, in which each new partial model is refined and therefore search models and lists of their possible orientations are updated along with the partial structure. (c) Superposition of (red, yellow) two molecules of MTH685 protein forming the AU and (green) the homologous protein Af0491 (PDB code 1p9q ) by second domains, showing that MR solution using the whole molecule as a search model is impossible. (d) Enlarged superposition of second domains (red) from chain A of the final structure, (blue) from a refined partial structure containing two of six domains and (green) from the homologue corrected according to the target sequence.
