Abstract

The conformation of ten purified tRNAs from Escherichia Coli has been investigated by means of the photo-induced cross-linking of 4Srd8 and Cyd13, which is sensitive to the juxtaposition of the two bases. Three tRNAs photo-react abnormally slowly; tRNAPhe, tRNAMet/m a and tRNAVal/2; a comparison with normally reacting species suggests that base 47 (Urd or modified Urd) is involved in a tertiary interaction in Class I tRNAs with the triplet 8, 14, 28. The UGA suppressor tRNATrp photoreacts significantly slower than the wild type. Thus the single base change Gua 24 to Ade induces a conformational change that alters the rate constant for the cross-linking reaction.
