Bacterial Cell Division Regulation: Characterization of the dnaH Locus of Escherichia coli

Abstract

The dnaH locus is the fourth gene to be identified as required for deoxyribonucleic acid polymerization in Escherichia coli. A temperature-sensitive mutant defective in this gene exhibited an abrupt decrease in rate of deoxyribonucleic acid synthesis when shifted to 42 C. The locus mapped in the proC-purE region of the chromosome by conjugation and was co-transducible with purE. dnaH+ is carried on the F′13 episome and is dominant over the dnaH− mutation.
