Additional NMR Experimental Information
Details	THE STRUCTURE WAS DETERMINED USING HOMONUCLEAR NMR SPECTROSCOPY, DETECTING INTERMOLECULAR NOES. RNA INTRAMOLECULAR RESTRAINTS WERE AS IN ABOUL-ELA ET AL, JMB 1995, AS THE NMR SPECTRA FOR THE RNA AS ABOUND BY THE LIGAND RBT203 SHOWED SIMILAR NOE AND CHEMICAL SHIFT PATTERNS TO THE LATTER
