Structured non-coding RNAs underline fundamental cellular processes, but determining their 3D structures remains challenging. We demonstrate herein that integrating NMR 1H chemical shift data with Rosetta de novo modeling can consistently return high-resolution RNA structures. On a benchmark set of 23 noncanonical RNA motifs, including 11 blind targets, Chemical-Shift-ROSETTA for RNA (CS-ROSETTA-RNA) recovered the experimental structures with high accuracy (0.6 to 2.0 Å all-heavy-atom rmsd) in 18 cases.
