For these reasons, the mechanisms by which porphyrins respond spectroscopically to various conditions and modifications have long been of vital interest to spectroscopists (Gouterman 1978).
While the photoreceptor has been characterized spectroscopically and biochemically in this organism, our knowledge of gravity-dependent orientation mechanisms has been rather limited.
