Interaction of NRT1.1 with the active kinase CIPK23 increases the vibrational entropy (∼2-fold) and has stabilizing effects on the collective motions. (A) Eigenvectors represent a relatively stable state of the A.NRT1.1.CIPK23 complex and the loss of loop dynamics that allow maintaining stable nitrate transport. (B) Formation of relatively stable large nitrate transport tunnel in the presence of CIPK23, with a large volume of 12,660 Å3. (C) and (D) show a large change in the volume of nitrate transport tunnel in the absence of CIPK23 interactions with monomer A. To see this figure in color, go online.
