Three Adjacent Transfer RNA Genes in Escherichia coli

A defective φ 80 transducing phage has been isolated that carries a small section of the E. coli chromosome from the region near argH (77 min). This phage contains three E. coli tRNA genes, termed gly Tsu+ 36, tyrT, and thrT. These genes specify the structures of tRNA2 Gly(su+ 36) tRNA2 Tyr, and tRN...

Description
Summary:A defective φ 80 transducing phage has been isolated that carries a small section of the E. coli chromosome from the region near argH (77 min). This phage contains three E. coli tRNA genes, termed gly Tsu+ 36, tyrT, and thrT. These genes specify the structures of tRNA2 Gly(su+ 36) tRNA2 Tyr, and tRNA3 Thr, respectively. Induction of a single lysogen bearing this phage brings about selective synthesis and amplification of only these three tRNAs.
