Photochemistry and Photophysics of Biliprotein Chromophores: A Case of Molecular Ecology
Biliproteins are widespread pigments in nature, and perform a variety of rather different functions (Kayser, 1985; Scheer, 1982; Braslaysky et al., 1983; Ruediger and Scheer, 1983): The phycobiliproteins occurring in cyanobacteria, rhodophytes and cryptophytes, function as photosynthetic light-harvesting pigments. Phytochromes are sensory photoreceptors in plants and algae, and the putative adaptochromes and photomorphochromes of cyanobacteria are probably also biliproteins. The bilirubinserum albumin conjugates are involved in transporting this poorly water-soluble pigment, and many invertebrates contain biliproteins which play a role in their pigmentation, but may have additional functions.
