title: Three tandemly repeated structural genes encoding tRNA(f1Met) in the metZ operon of Escherichia coli K-12.
abstract: The metZ operon of Escherichia coli K-12 consists of three tandemly repeated structural genes encoding tRNA(f1Met) separated by two well-conserved spacer sequences. A multicopy plasmid carrying an intact metZ operon is unstable, deleting tRNA(f1Met)-coding regions by RecA-dependent recombination during cell growth.
