Novel mechanism of hexamer ring assembly in protein/RNA interactions revealed by single molecule imaging.

abstract：:One surprisingly common element of RNA secondary structure consists of a hairpin capped by a four-base loop (or the tetraloop). Recently the 3-D structures of two RNA-tetraloops have been determined by NMR-studies. Both structures have a similar architecture: the first and the last bases of the loop form a hydrogen bo...
