A eukaryotic BLUF domain mediates light-dependent gene expression in the purple bacterium Rhodobacter sphaeroides 2.4.1.


The flavin-binding BLUF domain functions as a blue-light receptor in eukaryotes and bacteria. In the photoreceptor protein photo-activated adenylyl cyclase (PAC) from the flagellate Euglena gracilis, the BLUF domain is linked to an adenylyl cyclase domain. The PAC protein mediates a photophobic response. In the AppA protein of Rhodobacter sphaeroides, the… (More)
