Phytochromes are a widespread family of photosensory proteins first discovered in plants, which measure the ratio of red to far-red light to control many aspects of growth and development. Phytochromes interconvert between red-absorbing P(r) and far-red-absorbing P(fr) states via photoisomerization of a covalently-bound linear tetrapyrrole (bilin) chromophore located in a conserved photosensory core. From recent crystal structures of this core region, it has been inferred that the chromophore st ...[more]
