Abstract;The crystal structure of the Tll0078 protein from Thermosynechococcus elongatus BP-1, which contains a BLUF(a sensor of blue-light using FAD)domain bound to FAD was determined at 2.ANGS. resolution. The overall structure of BLUF domain consists of a five-stranded mixed-.BETA.-sheet with two .ALPHA.-helices running parallel with it. The isoalloxazine ring of FAD is accommodated in a pocket formed by several highly conserved amino acid residues in the BLUF domain. (author abst.)
