NMR Refinement
Method molecular dynamics
Details This natural sequence exhibits the same conformation as the 7BRG-substituted sequence, which has a much cleaner NMR spectrum. 10 relaxation matrix intensity-refined structures of the 7BRG form with the lowest energy were taken, the bromine atoms were replaced with hydrogen atoms, and the structures were subsequently subjected to distance-retrained molecular dynamics refinement.
