Abstract：
:Sporulation histidine kinases, which sense sporulation-specific signals and initiate phosphorelay reactions, are poorly conserved among Bacillus species. We found several putative genes for sporulation histidine kinases in the genome sequence of Paenibacillus polymyxa E681 and assayed the genes for complementation of sporulation mutants of Bacillus subtilis. One of these genes, Kin1377, significantly restored the sporulation deficiency of kinA kinB double mutant of B. subtilis, but not of B. subtilis spo0B mutant. These results indicated that Kin1377 requires B. subtilis Spo0B and possibly Spo0F to transfer phosphate to B. subtilis Spo0A. Another putative kinase, Kin1038, slightly restored the sporulation deficiencies of both kinA kinB double mutant and spo0B mutant of B. subtilis. However the sporulation deficiency of the B. subtilis spo0B mutant was significantly restored in the presence of both Kin1038 and P. polymyxa Spo0A. These results indicate that the overexpressed Kin1038 is able to interact directly with and activate P. polymyxa Spo0A, and that Spo0A can support spore formation in B. subtilis.
