Multicopy plasmids containing the hisDG region of Klebsiella
pneumoniae were mutagenized with transposon Tn5. The
resulting plasmids were examined for their ability to comple-
ment hisD and hisG mutations in Escherichia coli. The
physical location of Tn5 on each of the hisD::Tn5 and
hisG::Tn5 plasmids was determined by restriction endo-
nuclease analysis. By combining the two types of data, a
precise correlated physical and genetic map of the K. pneu-
moniae hisDG region was constructed. Based on this analysis,
the minimum sizes of the hisD and the hisG genes were
