==Structure of loop E FROM E. coli 5S RRNA==
-
Two new RNA structures portray how non-Watson-Crick base pairs and metal, ions can produce a unique RNA shape suitable for recognition by proteins., The crystal structures of a 62 nt domain of E. coli 5S ribosomal RNA and a, duplex dodecamer encompassing an internal loop E have been determined at, 3.0 and 1.5 A, respectively. This loop E region is distorted by three, "cross-strand purine stacks" and three novel, water-mediated noncanonical, base pairs and stabilized by a four metal ion zipper. These features give, its minor groove a unique hydrogen-bonding surface and make the adjacent, major groove wide enough to permit recognition by the ribosomal protein, L25, which is expected to bind to this surface.
