abstract = {Proton transport is indispensable for cell life. It is
believed that molecular mechanisms of proton movement
through different types of proton-conducting molecules have
general universal features. However, elucidation of such
mechanisms is a challenge. It requires
true-atomic-resolution structures of all key
proton-conducting states. Here we present a comprehensive
function-structure study of a light-driven bacterial inward
proton pump, xenorhodopsin, from Bacillus coahuilensis in
all major proton-conducting states. The structures reveal
that proton translocation is based on proton wires regulated
by internal gates. The wires serve as both selectivity
filters and translocation pathways for protons. The
cumulative results suggest a general concept of proton
translocation. We demonstrate the use of serial
time-resolved crystallography at a synchrotron source with
sub-millisecond resolution for rhodopsin studies, opening
the door for principally new applications. The results might
also be of interest for optogenetics since xenorhodopsins
are the only alternative tools to fire neurons.},
