【Significance】
Tubulin loop dynamics

Tubulin, an essential eukaryotic protein that plays an important role in cell division, is a target for anti cancer drugs. The binding of the anti-mitotic drug colchicine to tubulin is modulated by the conformational flip of a loop that also controls the polymerization of tubulin into microtubule. Flipped and un-flipped conformations of the loop are known but a detailed dynamic picture of the transition is poorly understood. Here we describe the flip by a reaction coordinate defined by two collective vectors—one captures the core flip and the other depicts the trigger to the flip.
