Protein sizes in number of amino acids (AA) include Tat- or Sec-dependent secretory signal peptide sequences, if predicted. Highly similar BurM and Bmi subtypes are grouped and the pairwise AA sequence identity to a representative member of these groups (strains GG4, ATCC 25416, C6786, or DWS 37UF10B-2) is shown in percentage. The type of immunity protein (BmiA, BimB) is specified. The localization of the bmi genes is indicated by their position relative to the corresponding burM gene: downstream (D) or upstream (U); same strand (+) or opposite strand (−). NA, not annotated.
