✦ Synopsis

Rcrynt eAperimenta1 evidence su:qests that in the proton pump bxteriorhodopun (RR) from Halotucterium &lot&m. two protons are transported across the membmne in each photocycle. FolloGn~ our coherent-state model fox the \Su;ll protein rhodopsin. \hich his a close structural similarity to BR. WC susest the occurrentx of a superfluid coherent ekctronic sti\te in the BR molecule. From this \e an show that the rrusnctic flux in BR is quantiscd and hence we predict thaz thr chxge of the moving ion cluster will be + 2e. and offer this as ;t tcntariw e&pkn.ttion of the eqeriment;tl results.
