Abstract excerpt
Phytochromes are chromoproteins found in plants and bacteria that switch between two photointerconvertible forms via the photoisomerization of their chromophore. These two forms, Pr and Pfr, absorb red and far-red light, respectively. We have characterized the biophysical and biochemical properties of two bacteriophytochromes, RpBphP2 and RpBphP3, from the photosynthetic bacterium Rhodopseudomonas palustris....
