Molecular cloning and DNA homology of plasmid-mediated β-lactamase genes
Molecular cloning of DNA fragments between 1.5 and 8kb from BamHI, EcoRI, HindIII, SalI, or Sau3A digests permitted the isolation of structural genes coding for TEM-1, ROB-1, OXA-1, OXA-3, OXA-4, OXA-5, PSE-1, PS...

Control of the argECBH cluster in Escherichia coli
The argECBH genes in Escherichia coli are tightly clustered, but argE is not controlled coordinately with argCBH. Furthermore, while nonsense mutations have been isolated in argC and argB which are polar for argH
