A Q63E Rhodobacter sphaeroides AppA BLUF domain mutant is locked in a pseudo-light-excited signaling state.

Abstract excerpt

The AppA BLUF photoreceptor from Rhodobacter sphaeroides contains a conserved key residue, Gln63, that is thought to undergo a shift in hydrogen-bonding interactions when a bound flavin is light excited. In this study we have characterized two substitution mutants of Gln63 (Q63E, Q63L) in the con...
