In Clostridium perfringens S40, spore germination-specific enzymes are synthesized during sporulation. Previous reports have demonstrated that two cortex-lytic enzymes, SleC and SleM, and a component of germination-specific protease, CspC, are located outside the cortex as an integral part of the dormant spore. In the present study, we examined the time and compartment of these enzymes’ gene expression using reverse transcription-PCR (RT-PCR) and fluorescence microscopy on green fluorescence protein (GFP)-fused proteins. These results suggested that CspABC, SleC, and SleM are synthesized in the mother cell compartment of sporulating cells, probably at stages II ~ III of sporulation, and that the expression of cspABC genes is tricistronic.
