This sequence occurs in Conus marmoreus (mollusc-hunting cone snail). However, the C-terminus has been amidated whereas it exists as a free-acid in the native form. sample The sample was a purified single peptide component but on dissolution displayed evidence of multiple conformations (manifest by peaks "brothering" in the N-terminal region). The structures shown are for the major solution conformer. The submitted conformer models are the 20 structures with the lowest energy. 50 20 2D NOESY DQF-COSY E-COSY 3.5 ambient 285 K The structures are calculated from a total of 82 distance restraints derived from 14 intra-residue, 42 sequential, 3 medium and 23 long range NOEs, and 4 dihedral restraints. torsion angle dynamics 8 closest to the average 2 mM MrIB-NH2 90% H2O/10% D2O Bruker collection XwinNMR 2.6 Biosym Technologies data analysis Felix 230 Brunger structure solution X-PLOR 3.851 Brunger refinement X-PLOR 3.851 500 Bruker ARX 750 Bruker AVANCE VAL 1 n 1 VAL 1 A GLY 2 n 2 GLY 2 A VAL 3 n 3 VAL 3 A CYS 4 n 4 CYS 4 A CYS 5 n 5 CYS 5 A GLY 6 n 6 GLY 6 A TYR 7 n 7 TYR 7 A LYS 8 n 8 LYS 8 A LEU 9 n 9 LEU 9 A CYS 10 n 10 CYS 10 A HIS 11 n 11 HIS 11 A HYP 12 n 12 HYP 12 A CYS 13 n 13 CYS 13 A CYS 13 n 14 NH2 14 A author_defined_assembly 1 monomeric A HYP 12 4-HYDROXYPROLINE A HYP 12 PRO 1.0000000000 0.0000000000 0.0000000000 0.0000000000 1.0000000000 0.0000000000 0.0000000000 0.0000000000 1.0000000000 1_555 x,y,z identity operation 0.0000000000 0.0000000000 0.0000000000 1 A A HIS HYP 11 12 146.34 16 A A HIS HYP 11 12 149.23 3 6.61 1.10 114.20 120.81 A A A CA CB SG CYS CYS CYS 4 4 4 N 4 9.72 1.10 114.20 123.92 A A A CA CB SG CYS CYS CYS 4 4 4 N 7 7.56 1.10 114.20 121.76 A A A CA CB SG CYS CYS CYS 4 4 4 N 10 7.47 1.10 114.20 121.67 A A A CA CB SG CYS CYS CYS 10 10 10 N 11 9.44 1.10 114.20 123.64 A A A CA CB SG CYS CYS CYS 4 4 4 N 13 9.88 1.10 114.20 124.08 A A A CA CB SG CYS CYS CYS 4 4 4 N 14 7.45 1.10 114.20 121.65 A A A CA CB SG CYS CYS CYS 4 4 4 N 1 A CYS 4 -109.33 43.68 1 A TYR 7 -159.39 -69.62 1 A LYS 8 -167.10 -47.42 1 A HIS 11 -152.79 -128.77 2 A CYS 4 -152.34 44.92 2 A TYR 7 -169.04 -56.41 2 A HIS 11 -153.59 -146.76 2 A HYP 12 -99.76 55.13 3 A TYR 7 65.17 -12.21 3 A LYS 8 -160.60 62.65 3 A LEU 9 54.59 -160.58 3 A HIS 11 -149.11 -139.62 3 A HYP 12 -119.04 58.47 4 A CYS 4 -160.01 28.27 4 A LYS 8 -163.20 -60.87 4 A HIS 11 81.88 -149.52 5 A CYS 4 -154.33 81.18 5 A TYR 7 63.02 -78.89 5 A LYS 8 -147.40 -39.60 5 A HIS 11 -147.87 -155.13 6 A LYS 8 -153.23 60.54 6 A LEU 9 57.86 -168.29 6 A HIS 11 -148.40 -134.61 6 A HYP 12 -101.85 42.83 7 A CYS 4 -155.18 49.28 7 A LYS 8 76.63 -14.95 7 A HIS 11 -152.73 -150.62 8 A CYS 4 -153.97 57.68 8 A TYR 7 -164.52 -73.65 8 A LYS 8 -161.63 -47.23 8 A HIS 11 -142.69 -153.96 9 A CYS 4 -114.48 55.41 9 A TYR 7 61.68 -79.15 9 A LYS 8 -148.02 -35.33 9 A HIS 11 -146.75 -138.01 10 A CYS 4 -149.54 58.77 10 A TYR 7 -159.65 -24.84 10 A LYS 8 -142.53 -66.80 10 A HIS 11 -150.68 -157.60 11 A CYS 4 -160.08 40.13 11 A TYR 7 65.06 -78.51 11 A LYS 8 -163.87 10.37 11 A HIS 11 78.44 -145.80 12 A TYR 7 -163.70 -40.26 12 A HIS 11 -152.65 -139.00 13 A CYS 4 -158.20 38.72 13 A TYR 7 -157.59 -26.90 13 A HIS 11 79.46 -155.95 14 A CYS 4 -156.22 43.38 14 A LYS 8 67.37 -4.29 14 A HIS 11 -149.45 -144.01 14 A HYP 12 -93.09 49.62 15 A CYS 4 -146.08 47.97 15 A TYR 7 63.36 -79.48 15 A LYS 8 -150.75 -28.02 15 A HIS 11 -148.06 -147.45 16 A TYR 7 64.81 138.27 16 A LEU 9 -169.27 107.76 16 A HIS 11 -150.22 -130.05 17 A CYS 4 -144.83 47.39 17 A TYR 7 -146.88 -49.76 17 A LYS 8 -108.72 -63.11 17 A HIS 11 -152.06 -146.46 17 A HYP 12 -109.20 48.38 18 A CYS 4 -160.33 77.13 18 A TYR 7 -142.19 27.24 18 A LYS 8 -154.95 -49.09 18 A HIS 11 -148.15 -154.33 19 A CYS 4 -147.32 45.50 19 A HIS 11 -148.67 -145.88 19 A HYP 12 -107.09 50.92 20 A CYS 4 -143.81 45.63 20 A TYR 7 -145.91 -39.26 20 A LYS 8 -97.18 -72.50 20 A HIS 11 -148.60 -147.53 20 A HYP 12 -108.52 46.36 SOLUTION STRUCTURE OF MRIB-NH2 1 N N disulf 2.013 A CYS 4 A SG CYS 4 1_555 A CYS 13 A SG CYS 13 1_555 disulf 2.022 A CYS 5 A SG CYS 5 1_555 A CYS 10 A SG CYS 10 1_555 covale 1.310 both A HIS 11 A C HIS 11 1_555 A HYP 12 A N HYP 12 1_555 covale 1.312 both A HYP 12 A C HYP 12 1_555 A CYS 13 A N CYS 13 1_555 covale 1.305 both A CYS 13 A C CYS 13 1_555 A NH2 14 A N NH2 14 1_555 TOXIN conotoxin, neuronal noradrenaline transporter, TOXIN CXL4_CONMR UNP 1 1 P58810 1 13 1IEO 1 13 P58810 A 1 1 13 BINDING SITE FOR RESIDUE NH2 A 14 A NH2 14 Software 2 A HYP 12 A HYP 12 2 1_555 A CYS 13 A CYS 13 2 1_555
