presence of two discrete and well-separated intensity decay lifetimes (ca. 1 and 5 ns) and intensity decay heterogeneity, of the neat sample suggests that the endogenous FMN senses a heterogeneous fluorescence quenching microenvironment at the active site of the luciferase. Free FMN in solution (isotropic environment), exhibits a single decay lifetime (5 ns), i.e., no intensity decay heterogeneity. Intensity decay heterogeneity of endogenous FMN is largely preserved in the presence of quinone. Averaged rotational rate of FMN increases with the increasing hydrophobicity of the quinone |
