Abstract: Cyanobacteriochromes (CBCRs) are photoreceptors consisting of single or tandem GAF (cGMP-phosphodiesterase/adenylate cyclase/FhlA) domains that bind bilin chromophores. Canonical red/green CBCR GAF domains are a well-characterized subgroup of the expanded red/green CBCR GAF domain family that… read more here.

DOI: 10.1038/s41598-017-14037-0
Abstract: Phytochromes (Phys) encompass a diverse collection of bilin-containing photoreceptors that help plants and microorganisms perceive light through photointerconversion between red light (Pr) and far-red light (Pfr)-absorbing states. In addition, Pfr reverts thermally back to Pr… read more here.

DOI: 10.1111/php.12793
Abstract: The dynamic behavior of the plant red/far‐red light photoreceptor phytochrome B (phyB) has been elucidated in natural and synthetic systems. Red light switches phyB from the inactive Pr state to the active Pfr state, a… read more here.
