Cloning and sequencing of a 27.8-kb nucleotide sequence of the 79 degrees-81 degrees region of the Bacillus subtilis genome containing the sspE locus.

The nucleotide sequence of a 27830-bp DNA segment in the 79 degrees-81 degrees region of the Bacillus subtilis genome has been determined. This region contains 29 complete ORFs including the sspE gene, which encodes a small acid-soluble spore protein gamma and locates on the one side terminal of our assigned region. A homology search for the products deduced from the 29 ORFs revealed that nine of them exhibit significant similarity to known proteins, e.g. proteins involved in an iron uptake system, a multidrug resistance protein, a chloramphenicol resistance protein, epoxide hydrolase, adenine glycosylase, and a glucose-1-dehydrogenase homolog.
