Structure And Dynamics Of RNA K-Turn Motifs
Original language description
Hinge-like RNA motifs occur at conserved positions in the 16S and 23S ribosomal RNAs, as revealed by x-ray crystallography of the 50S subunits of H. marismortui and D. radiodurans and the 30S subunit of T. thermophilus. The conformation of these asymmetric internal loops, called Kink-turns or K-turns, produces sharp, 120-degree bends in both phosphodiester backbones resulting in a V-shaped structure with an acute angle of ca.60 deg. between the RNA helices flanking the motif. In addition, some K-turns are specific binding sites for ribosomal proteins and take part in RNA-RNA tertiary interactions. We have carried out a set of explicit-solvent Molecular Dynamics (MD) simulations for selected K-turn motifs, including K-turn 38, and K-turn 42, and K-turn58 from the 23S ribosomal RNA of Haloarcula marismortui. The simulations reveal an unprecedented dynamical flexibility of the K-turns,indicating that these motifs function as very flexible internal loops linking rigid helix stems and capa
