High propeller twist and unusual hydrogen bonding patterns from the MD simulation of (dG)6 · (dC)6

Abstract
A molecular dynamics (MD) study of (dG)6 · (dC)6 including counter ions and 292 water molecules was made. The hydrogen bonding pattern and propeller twist angles for the mini‐helix are reported as averages for times spanning 21–30, 31–40, 41–50, and 51–60 ps. The propeller twist angles range from 18° to 38°. Bifurcated and interstrand neighboring base (twisted) hydrogen bonding patterns were found.
