Gene rearrangement of Bacillus cereus gerE. (a) Schematic of gene rearrangements of B. subtilis sigK and B. cereus gerE. The composite sigK and gerE genes after the rearrangement encode a sporulation-specific sigma factor, σK, and a transcriptional factor, GerE, respectively, which govern mother cell-specific gene expression at the late stage of sporulation. RNAP, RNA polymerase. (b) Whole nucleotide sequence of gerE from Bacillus cereus ATCC10987. Deduced amino acid sequence is shown under the nucleotide sequence. The gin element is inserted at position 138–146 nt (indicated by the red box). Nucleotides shaded green and purple correspond to the coding regions of 5′-gerE and gerE-3′, respectively. START, start codon; STOP, stop codon.
