Abstract

An analysis of the aminoacylation kinetics of unmodified yeast tRNAPhe mutants revealed that five single-stranded nucleotides are important for its recognition by yeast phenylalanyl-tRNA synthetase, provided they were positioned correctly in a properly folded tRNA structure. When four other tRNAs were changed to have these five nucleotides, they became near-normal substrates for the enzyme.
