NMR Refinement
MethodDetailsSoftware
Noesy assignments made with iterative method using CS, 3J, Hyper (dihedral), and Dyana for simulated annealing MD. Converged structures are further refined using NIH-xplor followed by CNS in explicit water shell (Nielges) . Full lenght sequence was carried through the refinement protocol, the disordered regions and hexHIS tag are not reported. Structure based on 595 constraints, 249 long range, 163 dihedral constraints and 36 H-bond constraints.VNMR

Additional NMR Experimental Information
DetailsStructure determined by Triple resonance NMR spectroscopy. Monomer in solution by NMR Tc = 8.6 +/- 0.1 ns (1D T1/T1rho +/- fit std). CIS peptide res. 19T-20P. Structure determined by triple resonance NMR spectroscopy. Coordinates reported from residue 5 to 82 section based on order parameter. AutoAssign used for backbone assignment, manually completed sidechain. 13C and 15N NOESY were assigned with AutoStructure. Dihedral angle restraints determined by HYPER . Assignment stats (excluding C-term tag): backbone 84.6%, sidechain 74.7%, aromatic (sc) 89.36%, VL methyl stereospecific 100%, unambiguous sidechain NH2 85.7%. Structure quality factor PSVS 1.3: ordered residues ranges alpha helix (7-17, 23-26,30-43, 67-76), b-strand (46-47, 64-65, 50-51, 56-57) [S(phi)+S(psi)]>1.8. RMSD 0.6 bb, 1.2 all heavy atoms. Rama: 95.8% most fav, 3.7% addtl. all., 0.3 gen. all.,0.3% disall. Procheck (psi-phi): 0.03/0.43 (raw/Z), Procheck (all): 1.18/-1.18 (raw/Z), MolProbity Clash: 27.67/-3.22 (raw/Z). RPF scores all assigned residues (fit of noesy peaklists to structure): Recall: 0.896, Precision: 0.90, F-measure: 0.898, DP-score: 0.70. Monomer by light scattering.
