NMR structure determination of large RNAs is often restricted by limited RDC information caused by chemical shift degeneracy. We established a general, time- and cost-effective methodology for the preparation of 13C/15N complementary labeled RNAs from a single plasmid. Applying this method to the 25 kDa BC1-DTE RNA, we were able to resolve severe chemical shift degeneracy, thereby almost doubling the number of RDC restraints in comparison to the conventional 13C,15N uniform-labeled RNA.
