Genetic characterization of the gene hupB encoding the HU-1 protein of Escherichia coli

The gene hupB encoding the HU-1(HU beta) protein of Escherichia coli was mapped between proC at min 9 and minA at min 10 on the K-12 genome by plasmid integration and chromosome transfer studies. Genetic studies using plasmid rescue techniques demonstrated that the lon gene is located very close to the 5' end of hupB and that the two genes are both transcribed clockwise on the E. coli map Bachmann, Microbiol.
