Recombinants between 5' deletion mutants of a tRNAVal3b gene which is inactive as an in vitro transcription template and a CRNAArg gene, which is an active in vitro template were made. The 5' flanking region of tRNAArg including 36 nucleotides of the coding sequence of the gene stimulated transcription of the tRNAVal3b, deleted to the +17 position, gene by over 50 fold. When the 5' flanking region of the tRNArg gene included 22 nucleotides of the coding sequence stimulation was reduced by a factor of 3. Thus the sequences between +22 and +36 of tRNAArg are required to permit maximum stimulation of tRNAVal3b in vitro template activity.
