Iron-related modification of bacterial transfer RNA.
Transfer RNAs isolated from E. coli grown in media where ferric iron is not freely available show well characterized chromatographic changes due to the absence of the methylthio moiety of ms2i6A. The altered tRNA molecules include tRNA trp tRNA tyr, tRNA phe and two minor tRNA ser species. It has been suggested that methylthiolation of tRNA affects its function in regulation. We now show iron-r...

isomorphous replacements, for clarification and possible decision among the several structures proposed. tRNA has long been known to be rich in minor base modifications (6, 20), of which the most common is methylation, and this occurs on all 4 major bases. Data presented at this symposium by Stulberg and Shugart (72) support the logical inference that these base modifications change the tertiar...
