LigPlot interaction schematic for Tat:NLSCPP importin- structure. Tat:NLSCPP intramolecular bonds are shown as solid purple lines, importin- intramolecular bonds are shown as strong orange lines. Importin- residues involved in hydrophobic contacts are shown as multiple red fanning lines. Corresponding atoms involved in hydrophobic contacts are shown with little orange fanning lines. Hydrogen bonds and their length are shown as green dotted lines.

Importin- interacting residues from Tat NLSCPP area. (A) Importin- shown in cyan (ribbons and surface view), Tat:NLSCPP shown in magenta (sticks). NLS residues visible within crystal structure, and bound for the N-terminal concave ARM domains of importin-, are shown in stereoview for 3D visualisation (B) Each P-site that interacts with importin- is displayed with each interaction highlighted with dashed lines.indexed, merged and scaled making use of iMosflm v.1.0.722 and AIMLESS23, 24 (Table 1). The structure was solved by molecular replacement using Phaser25, 31 with PDB 5FC8 as a model. Following rebuilding and refinement, the 2.0 resolution structure was refined to a RworkRfree of 0.160.19 utilizing iterative cycles of refinement and modelling in Phenix29 and COOT28 respectively. The final model consisted of 426 residues of importin-, 8 residues in the Tat:NLSCPP, and 319 water molecules. The N- and C-terminal amino acid residues in the Tat:NLSCPP peptide displayed poor density on account of flexibility, enabling only accurate placement in the protein peptide chain. Stereochemistry as well as other refinement statistics are presented in Table 1. of importin- exhibited an all -helical structure arranged as ten sequential armadillo (ARM) motifs as described previously6. The Tat:NLSCPP binds towards the major binding web page of importin- inside ARM domains two (Fig. 3A,B). You will find no NLS residues in the minor binding web-site, indicating that the NLS area is monopartite. The key chain of Tat residue Arg49 interacts using the side chain of importin- residue Asn235 in the P1 website (Figs 4 and 5). Tat residue Lys50 binds importin- in the P2 site where it types a salt b.
