Imino proton spectra of GSRapt. (a) Unlabeled RNA before laser pulse. (Inset) Chemical structure of DMNPE-hypoxanthine (Hyphυ). (b) [15N]uridine-labeled RNA, uridine residues as a result of 1H{15N}-detection after laser pulse with annotated NMR resonance assignment (31) of resolved residues. (c) Unlabeled RNA after laser pulse. (Inset) Chemical chemical structure of hypoxanthine (Hyp). (d) [15N]uridine-labeled RNA, guanosine residues as a result of 1H{14N}-detection after laser pulse with annotated NMR resonance assignment (31) of resolved residues.
