SUMMARY: Mutants of with deletions extending from the PBSX prophage, and in some cases removing and , have been found to be constitutive for vegetatively synthesized alkaline phosphatase. Such deletions were isolated by selecting for heat-resistant derivatives of a strain carrying a mutation causing heat-inducibility of the defective phage PBSX. These deletions remove the gene, a regulatory gene for alkaline phosphatase; it is concluded that the gene product exerts negative control on alkaline phosphatase synthesis. Deletion mapping, combined with previously published linkage data, indicates a gene order of PBSX-.
