The katX gene, which codes for the catalase in spores of Bacillus subtilis, is a forespore-specific gene controlled by sigmaF, and KatX is essential for hydrogen peroxide resistance of the germinating spore.

Abstract excerpt

Previous work has shown that the katX gene encodes the major catalase in dormant spores of Bacillus subtilis but that this enzyme has no role in dormant spore resistance to hydrogen peroxide. Expression of a katX-lacZ fusion began at approximately h 2 of sporulation, and >75% of the katX-driven beta-galactosidase was packaged into the mature spore. A mutation in the gene coding for the sporulation-specific RNA...
