NMR spectra showing enhanced resolution afforded by site selective labeling of A-Site RNA bound to paromomycin. The experiments were performed on the A-Site RNA A site-selectively ¹³C-GTP and CTP labeled and B uniformly ¹³C-GTP and CTP labeled. 2D non-constant time HSQC spectra of the base region. The cytosine (Cyt) and Uracil (Ura) C6 resonances are boxed to highlight the absence of labeling in selectively labeled sample
