Genetic Mapping of the Bacitracin Synthetase Gene(s) in Bacillus licheniformis

SUMMARY: The map position of a mutation in the bacitracin synthetase gene(s) in Bacillus licheniformis ATCC 10716 was determined by transduction with phage SP-15. Results indicate that it is linked to the lys and trp loci and is distinct from the known sporulation loci on the chromosome of Bacillus licheniformis. The defect(s) of the enzyme complex were analysed in terms of its ability to bind covalently 14C-labelled amino acid precursors of the bacitracin molecule.
