YtvA is a bacterial flavo-protein related to plant phototropin. The photochemistry of YtvA and of its isolated LOV domain (YtvA-LOV) has been characterized by optical, mass spectrometric and photocalorimetric methods. The energy content (E390) of the FMN-C4a-thiol photoadduct (YtvA390 and YtvA-LOV390) and its structural volume change (deltaV390), with respect to the parent state, have been determined by means of Laser Induced Optoacoustic Spectroscopy (LIOAS). The high value of E390, 136 and… CONTINUE READING
