PrtS protease domain alignments and amino acid sequence identity percentages (reference: PrtS from STH LMD-9). The domains of PrtS are: SS, signal sequence; PP, propeptide; PR, catalytic domain; A, globular domain; H, helical domain; W, cell wall domain; AN, cell wall anchor. Domain length is indicated in number of amino acids (aa). The two biochemically characterized sequences of PrtS from strains CNRZ385 [113] and 4F44 [112] were added
