The archaeal protein L7Ae forms part of a protein complex in the ribosome that specifically recognizes and binds to kink-turn RNA. In this complex, L7Ae directly interacts with the oligonucleotide and creates a functional arrangement for site-specific 2-O-methylation. We report the solution NMR backbone assignment of Methanocaldococcus jannaschii L7Ae (117 residues, 12.7?kDa) in the ligand-free state and when bound to a 25 nucleotide C/D box kink-turn mimic RNA.
