Abstract excerpt
Various tRNA transcripts were constructed to study the identity elements of E.coli tRNA(Arg) and tRNA(Lys). Exchange of the anticodon of the major tRNA(Arg) from ACG to either CCG or CCU did not result in a significant loss of arginine acceptor activity, whereas not only that to UUU but also that to ACA or ACC decreased the activity. Base substitutions and deletion at A20 also impaired the arginine charging...
