Abstract


Eleven native transfer RNAs have been prepared so as to maintain their Mg2+ content. Their aqueous Raman spectra show a high, relatively constant amount of order in the ribophosphate backbone, as indicated by the ratio 1.73 +/- 0.05 for I814/I1100 in all samples. Variation in the effectiveness of stacking of guanine and adenine bases is seen, though most of the transfer RNAs studied have a comparable degree of stacking to that found in phenylalanine transfer RNA from yeast, whose tertiary structure has been determined by X-ray crystallography. The spectrum of Escherichia coli 5S RNA indicates that the stacking efficiency of the guanine bases is much higher in 5S RNA than in yeast in phenylalanine transfer RNA, while that of the adenine bases is lower.
