Description
  • Molecular dynamics (MD) simulations of Kink-turn (K-turn) RNA motifs reveal hinge-like motions on the nano-second (ns) timescale. K-turn motifs are asymmetric internal loops found at conserved positions in the 16S and 23S ribosomal RNAs, and characterized by sharp bends in both phosphodiester backbones producing V-shaped structures. The bend is stabilized by non-Watson-Crick basepairs involving the minor (shallow) grooves of the helices. We have carried out a set of explicit-solvent MD simulations for selected K-turn motifs from 23S ribosomal RNA, Kt-38 (located at the base of the A-site finger), Kt-42 (located at the base of the L7/L12 stalk in the factor-binding site) and Kt-58 (located in Domain III). On a nano-second timescale, K-turns sample isoenergetic conformational substates. The simulations reveal the presence of long-residency sites for water, one of which is located close to the sharp turn of the phosphodiester backbones and, when occupied, mediates minor-groove interactions between the st
