Figure 5
Sequence alignment of YkfC from B. subtilis and B. cereus, dipeptidyl-peptidase VI (DPP VI) from B. sphaericus and a γ-D-glutamyl-L-diamino acid endopeptidase from A. variabilis (AvPCP). The sequence numbering and secondary-structure elements of YkfC from B. cereus and AvPCP are indicated at the top and bottom, respectively. The alignment was generated by merging and manually editing the structure-based sequence alignment of BcYkfC and AvPCP with the sequence alignment of the top three sequences. The active-site residues are marked with colored dots at the bottom (blue, S2; orange, S1; red, catalytic triad; green, potential S′ sites). |
