Energy transformations early in the bacteriorhodopsin photocycle revealed by DNP-enhanced solid-state NMR

By exploiting dynamic nuclear polarization (DNP) at 90 K, we observe the first NMR spectrum of the K intermediate in the ion-motive photocycle of bacteriorhodopsin. The intermediate is identified by its reversion to the resting state of the protein in red light and by its thermal decay to the L inte...
