abstract = {Rhodopsins, most of which are proton pumps generating
transmembrane electrochemical proton gradients, span all
three domains of life, are abundant in the biosphere, and
could play a crucial role in the early evolution of life on
earth. Whereas archaeal and bacterial proton pumps are among
the best structurally characterized proteins, rhodopsins
from unicellular eukaryotes have not been well
characterized. To fill this gap in the current understanding
of the proton pumps and to gain insight into the evolution
of rhodopsins using a structure-based approach, we performed
a structural and functional analysis of the light-driven
proton pump LR (Mac) from the pathogenic fungus
Leptosphaeria maculans. The first high-resolution structure
of fungi rhodopsin and its functional properties reveal the
striking similarity of its membrane part to archaeal but not
to bacterial rhodopsins. We show that an unusually long
N-terminal region stabilizes the protein through direct
interaction with its extracellular loop (ECL2). We compare
to our knowledge all available structures and sequences of
outward light-driven proton pumps and show that eukaryotic
and archaeal proton pumps, most likely, share a common
ancestor.},
