From a recombinant lambda phage, we have determined a 317-bp sequence containing a mouse tRNAiMet gene. The coding region is precisely homologous to mammalian tRNAiMet if post-transcriptional modifications (including addition of the 3'-terminal CCA) are not considered. The gene does not contain introns and has a typical RNA polymerase III termination site in the 3'-flanking region. It is transcribed by RNA polymerase III in the HeLa cell S-100 system in vitro. Notably, the 5'-flanking region of the mouse tRNAiMet gene shares a "patchwork" pattern of homology with one of the human tRNAiMet genes of Santos and Zasloff [Cell 23 (1981) 699-710]. The 5'-flanking regions of the two genes contain strings of nucleotides, 6 to 32 bp in length, the homology of which is 76-100%. These are separated by short strings of unrelated nucleotides. This is one of the first examples of tRNA genes containing homologous 5'-flanking regions isolated from distantly related mammals. We also report a novel method for constructing deletion mutants of sequences cloned in M13 vectors.
