Structures were refined by using data imputation (. Cano, C., Brunner, Baskaran, K., K. Elsner, R., Munte, C. E. and Kalbitzer, H. R. (2009) Protein structure calculation with data imputation: the use of substitute restraints. J. Biomol. NMR 45, 397-411) and refinement in explicut water (Linge, J.P., Williams, M.A., Spronk, C.A.E.M., Bonvin, A.M.J.J. and Nilges, M. (2003). Refinement of protein structures in explicit solvent. Proteins 50, 496-506).
