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…

Crystal Structure of Ribosome with Release Factor RF3

Members of the Noller lab recently published a 3.3 Å resolution structure of a complex containing the ribosomal release factor (RF3) locked in its GTP-bound state (mimicked using GDPNP) in association with the *E. coli* 70s ribosome. Crystallographic data for this project was collected at the SIBYLS beamline MX station. > The class II release…
