Abstract excerpt
Phytochromes are red/far-red photosensory proteins that regulate adaptive responses to light via photoswitching of cysteine-linked linear tetrapyrrole (bilin) chromophores. The related cyanobacteriochromes (CBCRs) extend the photosensory range of the phytochrome superfamily to shorter wavelengths of visible light. CBCRs and phytochromes share a conserved Cys residue required for bilin attachment. In one CBCR...
