N2 - A 2.4-kilobase fragment of the Bacillus subtilis chromosome containing the wild-type spoOA gene derived from the φ105dspoOA+-Bc-1 transducing phage was cloned onto plasmid pBR322 in Escherichia coli. A recombinant plasmid harboring the mutant spoOA12 allele on the 2.4-kilobase insert was also constructed from the φ105dspoOA12-1 phage DNA and pBR322. Protein products synthesized in reponse to plasmid DNA in a DNA-directed cell-free system derived from E. coli were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. A protein of approximately 27,500 daltons synthesized with the recombinant plasmid DNA harboring the wild-type spoOA gene as template was not formed with the recombinant plasmid DNA harboring the spoOA12 allele. Since the spoOA12 mutation is a nonsense mutation, we conclude that the 27.5-kilodalton protein is the product of the spoOA gene.
