The Bacillus subtilis 168 chromosome from sspE to katA.

We have cloned and sequenced a 24.5 kb region of the Bacillus subtilis 168 chromosome spanning the sspE and katA genes. The region contains a ribosomal RNA operon, rrnD, a tRNA gene set, trnD and 17 ORFs, 16 with putative ribosome-binding sites. Four of the ORFs (ORF2, ORF14, ORF16 and ORF17) match to known B. subtilis genes (sspE, thiA, senS and katA). Eight of the remaining ORF products show similarities with proteins present in the databases, including an ATP-binding transport protein, a glutamate-1-semialdehyde aminotransferase, a thiol-specific antioxidant protein, a mitomycin radical oxidase and a ferric uptake regulation protein.
