Abstract
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. 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.
