Weekly RNA News - Week IV - January 2011

Yelena Koldobskaya @ U. Chicago and collaborators propose a new method to crystallize RNA's using chaperones:

There is a protein called Signal Recognition Particle (SRP), it's made of a protein part and a 4.5S RNA. This protein is important in the mechanism of action of the ribosome and Leandro F. Strozi at Grenoble and collaborators have "describe the cryo-EM structure of the E. coli ribosome–SRP–FtsY complex in the early conformation, demonstrating that the ribosome acts as a platform that optimally positions critical SRP regions for receptor recruitment":

The third week of January came with a special issue on surface chemistry in PNAS.
Two interesting articles, one mentions what has been learned using DOS analysis from DFT calculations on surface catalysis, and another a general review on surface processes and the need for taking into account the nucleus, not just electronic structure.
