MethodDetailsSoftware
Automated methods were used for backbone chemical shift assignment and iterative NOE refinement. Final structures were obtained by molecular dynamics in explicit solvent.Residues 1-27 and 95-116 of the construct were disordered and were excluded from the model. After initial calculations without zinc, the zinc atom was constrained in a tetrahedral geometry using distance restraints to each coordinating CYS SG and HIS NE2 of 2.3 A and 2.0 A, respectively.XwinNMR
