Methods of use of genes of pyridoxal 5'-phosphate biosynthesis in Bacillus subtilis: avirulent strains for vaccines, and methods for identification of antibacterial agents

摘要

Methods and compositions comprising a pathogenic bacterial strain having a non-reverting mutation in a pdx gene encoding an enzyme involved in pyridoxal-5'-phosphate synthesis are provided, for use in vaccines, and methods for identification of inhibitors of the enzyme for use as an antibacterial agent are provided.
