Further evidence for a single leucyl transfer ribonucleic acid synthetase capable of charging five leucine transfer ribonucleic acids in Escherichia coli.

Five components of leucine transfer ribonucleic acid in Escherichia coli separated on a reversed phase column were charged with radioactive leucine. Each labeled leucyltRNA was subjected to an exchange reaction with unlabeled E. coti tRNA in which the labeled leucine could be transferred from one leucine tRNA to another. The ‘exchange product, when analyzed… CONTINUE READING
