Phytochromes are a widespread family of red/far-red responsive photoreceptors first discovered
in plants, where they constitute one of the three main classes of photomorphogenesis …

Photosensory proteins enable living things to detect the quantity and quality of the light
environment and to transduce that physical signal into biochemical outputs which entrain their …

Phytochromes were long thought to have evolved in non-motile photosynthetic eukaryotes
for adaptation to unfavorable light environments, but recent studies suggest that …

The biliprotein phytochrome regulates plant growth and developmental responses to the
ambient light environment through an unknown mechanism. Biochemical analyses …

The discovery of cyanobacterial phytochrome histidine kinases, together with the evidence
that phytochromes from higher plants display protein kinase activity, bind ATP analogs, and …

Cyanobacteria are unique among bacteria in performing oxygenic photosynthesis, often
together with nitrogen fixation and, thus, are major primary producers in many ecosystems. The …

The isolation and chromatographic purification of chromophore-containing peptides from
the PR form of phytochrome treated with pepsin and thermolysin are described. From the …

Biliproteins and bilipeptides subjected to discontinuous sodium dodecyl sulfate-polyacrylamide
gel electrophoresis in the presence of zinc acetate form a complex which fluoresces an …

Light perception by the plant photoreceptor phytochrome requires the tetrapyrrole chromophore
phytochromobilin (PϕB), which is covalently attached to a large apoprotein. Arabidopsis …

The bilin prosthetic groups of the phytochrome photoreceptors and the light-harvesting
phycobiliprotein antennae arise from the oxygen-dependent ring opening of heme. Two …
