abstract = {Blue-light photoreceptors containing
light–oxygen–voltage (LOV) domains regulate a myriad of
different physiological responses in both eukaryotes and
prokaryotes. Their light sensitivity is intricately linked
to the photochemistry of the non-covalently bound flavin
mononucleotide (FMN) chromophore that forms a covalent
adduct with a conserved cysteine residue in the LOV domain
upon illumination with blue light. All LOV domains undergo
the same primary photochemistry leading to adduct formation;
however, considerable variation is found in the lifetime of
the adduct state that varies from seconds to several hours.
The molecular mechanism underlying this variation among the
structurally conserved LOV protein family is not well
understood. Here, we describe the structural
characterization of PpSB1-LOV, a very slow cycling
full-length LOV protein from the Gram-negative bacterium
Pseudomonas putida KT2440. Its crystal structure reveals a
novel dimer interface that is mediated by N- and C-terminal
auxiliary structural elements and a unique cluster of four
arginine residues coordinating with the FMN-phosphate
moiety. Site-directed mutagenesis of two arginines (R61 and
R66) in PpSB1-LOV resulted in acceleration of the dark
recovery reaction approximately by a factor of 280. The
presented structural and biochemical data suggest a direct
link between structural features and the slow dark recovery
observed for PpSB1-LOV. The overall structural arrangement
of PpSB1-LOV, together with a complementary phylogenetic
analysis, highlights a common ancestry of bacterial LOV
photoreceptors and Per-ARNT-Sim chemosensors.},
