Abstract
The L7Ae superfamily of proteins are widespread, with important roles in the ribosome, snoRNP structures, and spliceosome assembly. They bind extremely tightly and selectively to k-turn structures in RNA. An alpha helix is placed in the widened major groove on the outside of the RNA kink in order to make both sequence-specific and non-specific interactions. The interaction is disrupted by N6-methylation of adenine at a specific position, and this can modulate the assembly of human box C/D snoRNP. L7Ae-k-turn complexes can be used in nanoconstruction to generate a variety of molecular objects.
