abstract = {Microbial rhodopsins are photoreceptor proteins that
convert light into biological signals or energy. Proteins of
the xanthorhodopsin family are common in eukaryotic
photosynthetic plankton including diatoms. However, their
biological role in these organisms remains elusive. Here we
report on a xanthorhodopsin variant (FcR1) isolated from the
polar diatom Fragilariopsis cylindrus. Applying a
combination of biophysical, biochemical and reverse genetics
approaches, we demonstrate that FcR1 is a plastid-localized
proton pump which binds the chromophore retinal and is
activated by green light. Enhanced growth of a Thalassiora
pseudonana gain-of-function mutant expressing FcR1 under
iron limitation shows that the xanthorhodopsin proton pump
supports growth when chlorophyll-based photosynthesis is
iron-limited. The abundance of xanthorhodopsin transcripts
in natural diatom communities of the surface oceans is
anticorrelated with the availability of dissolved iron.
Thus, we propose that these proton pumps convey a fitness
advantage in regions where phytoplankton growth is limited
by the availability of dissolved iron.},
