Model of UV-B sensing by UVR8, a heme-free photoreceptor.
Researchers from [Scripps Research Institute](http://www.scripps.edu/news/press/20120209getzoff.html) and the University of Glasgow have published a detailed molecular model of how UVR8, a unique heme-free plant photoreceptor, senses UV-B light via an intricate interacting mesh of Tryptophan residues positioned at the UVR8 dimer interface which ultimately results in the disruption of a salt bridge and dissociation of the…
