    Supramolecular catalytic assemblies attract enormous interest due to their activity that rivals natural enzymes. Using ab initio molecular dynamics, the authors show that a gold catalyst in a Ga4L612- nanocage, while impeded by reorganization energy, is accelerated by hosting a catalytic water molecule.

    Studying the single-molecule behavior of host-guest complexes can provide fundamental insights into their supramolecular interactions. Here, the authors use the scanning tunneling microscopy break junction technique to show that encapsulation of a C60 molecule significantly enhances the conductance of an organoplatinum metallocycle; mechanical stretching of the junction releases the guest, returning the conductance to free-host level.

    The mechanism by which macromolecular catalysts use energy from exergonic reactions to move, adapt, and assemble has been unclear. In this Perspective article, R. Dean Astumian shows that in addition to disequilibrium of the catalyzed reaction, kinetic asymmetry is the essential feature required to drive non-equilibrium response by an information ratchet mechanism.
