Solution structure of the ribbon disulfide bond isomer of alpha-conotoxin AuIB
A New Level of Conotoxin Diversity, a Non-native Disulfide Bond Connectivity in alpha -Conotoxin AuIB Reduces Structural Definition but Increases Biological Activity.
1MXN contains Solution structure of the same protein with native disulfide bond connectivity
The peptide was synthesised by BOC chemistry.
structures with the least restraint violations,structures with the lowest energy
140 noe restraints were used including 4 long and 13 medium range noes, also 3 dihedral angles were included
simulated annealing, molecular dynamics, energy minimisation in a CHARM force field
