FIGURE 2.

Alignment of amino acid sequences of PeDPP11, PgDPP11, and PgDPP7. The amino acid sequence of PeDPP11 was compared with those of PGN0607/PgDPP11 and PGN1479/PgDPP7 from P. gingivalis and residues 232–250 of GluV8 carrying an essential Ser²³⁷ (60). Hyphens represent gaps introduced for maximal matching. Common amino acid residues are marked with asterisks, whereas those matched in two DPPs are indicated by dots. Amino acids corresponding to the regions used for amplification of PeDPP11 with degenerate primers are underlined. Amino acid residues to form the active triad of PeDPP11 predicted by comparison with those of PGN0607 and PgDPP7 are indicated by arrows.
