Steady state emission of the fluorescent intermediate of Anabaena Sensory Rhodopsin as a function of light adaptation conditions

- Fluorescence spectra of light- and dark-adapted bR and ASR protein samples reported.
- The dark- and light-adapted ASR fluorescence spectra are fully characterized for the first time.
- The pure retinal isomer fluorescence spectra, and quantum yields are deduced.
- The average radiative lifetimes of the retinal isomers are found to be isomer-dependent.
- Observation related to configuration-dependent transition dipole moment.
