This work studies the way collision cross-section measurements can guide the modelling of large protein assemblies represented as super coarse-grain objects (i.e. a single big sphere per protein).

We show that there exists a relationship between spheres overlap and collision cross-section that can be leveraged to define modelling restraints on a per-case scenario.

On a maybe less serious note, this work meets the stringent requirements of the “Palatinate Challenge” set up within Durham University computational chemistry groups.
