NettetCyanobacteriochromes (CBCRs) are photosensory proteins found in cyanobacteria and are distantly related to the widespread phytochromes. Whereas plant phytochromes exhibit responses to red and far-red light, CBCRs use the same photoisomerization of a linear tetrapyrrole (bilin) chromophore to respond to a wide range of colors. NettetTheir multidomain structure and autocatalytic incorporation of linear tetrapyrrole chromophores make phytochromes attractive molecular templates for the development of light-sensing probes. A subclass of bacterial phytochromes (BphPs) utilizes heme-derived biliverdin tetrapyrrole, which is ubiquitous in mammalian tissues, as a chromophore.
