Twisting angle τ (first row), and the out-of-plane bending angle χN (second row) value fluctuation during the 100 ns of MD simulation by 1 (first column), 2 (second column) and 3 (third column). Black and red thin lines instantaneous values in Mnr A and Mnr B, respectively, while green thin lines are those in water. The running average values are calculated over 200 ps for τ and χN (blue and yellow thick lines for Mnr A and Mnr B, respectively). The average τ and χN angles in water are shown in maroon.
