Sequence alignments of Spo0A. a Nucleotide sequence alignment of WT and M150B Spo0A region of interest. Nucleotides are numbered from the beginning of the gene. The 8 bp repeat surrounding the deleted region is bold and in red. b Amino acid residue alignment of the well-studied Bacillus subtilis (Bsu) against Cpa WT and M150B. Secondary structures based on Bsu from Lewis et al. [25] show conserved beta sheets (arrows) and alpha helices (bars) as well as the linker region (dashed line). Similarity is shown by red bars (identity) or green plus symbols (conservative). Helix-turn-helix DNA-binding motif is indicated by a purple bar, and the σ^A-activating region is shown with an orange bar
