Lowest frequency modes of MTERF1 adapt superhelical pitch and radius and may permit binding to B-DNA. (A) The lowest frequency ANM mode of MTERF1 is an axial motion, white and red surfaces of Cα atoms denote positive and negative displacements, respectively. (B) The next lowest frequency ANM mode of MTERF1 is a radial motion, white and blue surfaces of Cα atoms are positive and negative displacements, respectively. (C) and (D) are cartoons of motions above, pitch and radius, respectively.
