This review adds the bilin-binding phytochromes to the Chemical Reviews thematic issue
“Optogenetics and Photopharmacology”. The work is structured into two parts. We first …

Widespread phytochrome photoreceptors use photoisomerization of linear tetrapyrrole
(bilin) chromophores to measure the ratio of red to far-red light. Cyanobacteria also contain …

Certain cyanobacteria alter their photosynthetic light absorption between green and red, a
phenomenon called complementary chromatic acclimation. The acclimation is regulated by …

The phytochrome superfamily comprises three groups of photoreceptors sharing a
conserved GAF (cGMP-specific phosphodiesterases, cyanobacterial adenylate cyclases …

Cyanobacteriochromes (CBCRs) are members of the phytochrome superfamily of
photosensor proteins that bind a bilin chromophore. CBCRs exhibit substantial diversity in …

The initial light-induced processes of the photochromic, phycocyanobilin-binding GAF
domain of Slr1393 from Synechocystis sp. PCC6803 have been studied by ultrafast transient …

Phytochromes are a diverse family of bilin-binding photoreceptors that regulate a wide
range of physiological processes. Their photochemical properties make them attractive for …

Cyanobacteriochromes (CBCRs) are bilin-binding photosensors of the phytochrome
superfamily that show remarkable spectral diversity. The green/red CBCR subfamily is …

Phytochrome and cyanobacteriochrome utilize a linear methine-bridged tetrapyrrole (bilin)
to control numerous biological processes. They show a reversible photoconversion between …

Cyanobacteriochromes (CBCRs) are phytochrome-related photosensors with diverse
spectral sensitivities spanning the entire visible spectrum. They covalently bind bilin …
