FIG. 4.

Alignment of Tap1 amino acid sequences. (A) Identical amino acids from three treponemes are boxed and shaded with SHADYBOX, which reveals the conserved region near the carboxyl terminus. The dark inverted triangle indicates the location of the point of insertion for the erythromycin resistance cassette into the T. denticola tap1 gene to generate a Tap1-deficient mutant. (B) Alignment of the conserved C-terminal region of T. denticola Tap1 with FliK of S. typhimurium (16). Identical amino acids are boxed and shaded as described above.
