Dynamic hydrogen bonding and DNA flexibility in minor groove binders: molecular dynamics simulation of the polyamide f-ImPyIm bound to the Mlu1 (MCB) sequence 5'-ACGCGT-3' in 2:1 motif.Molecular dynamics simulations of the DNA 10-mer 5'-CCACGCGTGG-3' alone and complexed with the formamido-imidazole-pyrrole-imidazole (f-ImPyIm) polyamide minor groove binder in a 2:1 fashion were conducted for 50 ns using the pbsc0 parameters within the AMBER 12 software package.

pbsc0 parameters
The change in DNA structure upon binding of f-ImPyIm was evaluated via minor groove width and depth, base pair parameters of Slide, Twist, Roll, Stretch, Stagger, Opening, Propeller, and x-displacement, dihedral angle distributions of ζ, ε, α, and γ determined using the Curves+ software program, and hydrogen bond formation.
