Here, it is shown how a protein heterodimer with multiple flexibilities, the RNA polymerase I subcomplex A14/A43, could be crystallized with the use of an iterative procedure of predicting flexible regions, experimentally testing and improving these predictions and combining deletions of flexible regions in a stepwise manner. This strategy should enable the crystallization of other proteins and subcomplexes with multiple flexibilities, as required for hybrid structure solution of large macromolecular assemblies. access_permission:modify_annotations: true access_permission:can_print_degraded: true description: The removal of flexible protein regions is generally used to promote crystallization, but advanced strategies to quickly remove multiple flexible regions from proteins or protein complexes are lacking.
