Bacterial phytochrome photoreceptors (BphPs) ... possess the near-infrared (NIR) absorbance spectra that make them promising molecular templates to design NIR fluorescent proteins (FPs) and biosensors
Interestingly, natural Bacterial Phytochrome Photoreceptors (BphPs) utilize the low molecular weight biliverdin, found in most mammalian tissues, as a photoreactive chromophore. Due to their near-infrared absorbance BphPs are preferred templates for designing optical molecular tools for applications in mammals.
The paper reports bacteriophytochrome-derived photoactivatable near-infrared fluorescent proteins.

The review compares phenotypes of current BphP-based near-infrared fluorescent proteins with fluorescent proteins derived from cyanobacteriochromes and allophycocyanins.
Bacterial phytochromes, some cyanobacteriochromes, and allophycocyanins are promising molecular templates for designing near-infrared fluorescent proteins and biosensors.
Bacterial phytochrome photoreceptors use biliverdin, a chromophore found in most mammalian tissues, which supports their use as templates for mammalian optical tools.
BphPs spectrally complement existing genetically encoded probes.
Because of their near-infrared absorbance, BphPs are preferred templates for designing optical molecular tools for applications in mammals.
