Thoms, C. Barrio-Garcia, E. Hurt, and R. Beckmann interpreted EM data. J. Baßler and E. Hurt wrote the manuscript.

NMR structure calculation

A list of chemical shift assignments and 13C- and 15N-filtered 3D NOESY data were provided as input to PONDEROSA-C/S (Lee et al., 2014), which with its refinement option solved the initial structure. PONDEROSA-C/S incorporates TALOS-N (Shen and Bax, 2013) for the generation of structural restraints from chemical shifts and CYANA (Güntert, 2004) for structure determination. Next, hydrogen bond constraints were generated by predictions from CYANA, TALOS-N, PSIPRED (Buchan et al., 2013), analysis of NOESY spectra and the initial structure. Analysis was aided by use of Ponderosa Analyzer, NMRFAM-SPARKY (Lee et al., 2015) with the Ponderosa plug-in, and PyMOL. Ponderosa Analyzer was used to validate and refine distance and angle constraints and to export these to the Ponderosa Client for iterative structure calculations by the Ponderosa Server. Water refinement by XPLOR-NIH (Schwieters et al., 2003) was carried out by the Ponderosa Server. The final structure, as represented by 20 models, was analyzed by the protein structure validation software suite (PSVS; Bhattacharya et al., 2007).
