Abstract

To establish the light-color modulation mechanism of the firefly bioluminescence, we investigated the spectroscopic properties of the phenolate anion (1-O−) generated from 5,5-dimethyloxyluciferin (1-OH) under various base/solvent combinations. Observed fluorescent behavior of 1-O− verifies that the light emitter of firefly bioluminescence is the excited singlet state of keto-form of oxyluciferin phenolate anion (OL−) in the mechanism. Especially, a bonding interaction between OL− and a protonated basic moiety in the active site of a luciferase plays an important role in modulation of the pi-electronic property of the singlet-excited state of OL− for multicolor bioluminescence.
