Structure comparison of the catalytic domain of P60_tth with YkfC from B. cereus. (a) Primary-sequence alignment of P60_tth with YkfC from B. cereus. The secondary structures of the two proteins are indicated. The red sphere indicates the catalytic triad, while the blue spheres indicate other residues that are predicted to be involved in forming the catalytic site. (b) Superposition of the three-dimensional crystal structures of P60_tth (violet) and B. cereus YkfC (grey; PDB entry 3h41 ). The strand and helix numbering corresponds to that of P60_tth. (c) Comparison of active sites in the two crystal structures displayed as a cross-eyed stereoview. The colour code is the same as in (b).
