Abstract
The structural gene for alkaline phosphatase (phoA) of Escherichia coli was cloned into the PstI site of pBR322, from a transducing bacteriophage, lambda p(phoA-proC). The restriction map of the plasmid was established. Based upon this information, several phoA deletion plasmids as well as a smaller phoA+ plasmid were constructed. The genetic map and restriction map were correlated by recombination analysis. Cells carrying one of the phoA+ plasmids overproduce alkaline phosphatase 10-fold upon phosphate limitation. However, both regulation and processing of the enzyme were found to be normal.
