RESUMO
The high resolution nuclear magnetic resonance (NMR) spectra of hydrogen-bonded protons in four tRNAs have been studied at 270 MHz. The relative intensity of the resonances between -11 ppm and -15 ppm of Escherichia coli tRNA1Val indicate that there are 26 ± 3 protons, while only 20 are expected from secondary structure Watson-Crick hydrogen bonds in the cloverleaf structure. Several possible candidates for these extra resonances are suggested by tertiary interactions observed in recent crystallographic studies.
