Figure 1
The overall structure of C. perfringens sortase D. The secondary structure of C. perfringens sortase D monomer A is represented by red 310-helices and α-helices and yellow β-strands (PDB entry 4d70
). The N- and C-termini of the enzyme are indicated. The conserved catalytic triad consisting of His109 (blue), Cys171 (purple) and Arg178 (orange) is shown. The yellow β-strands form the β-barrel structure which is typically observed in the sortase family of enzymes (right-hand side). Figures were generated using PyMOL (v.1.5.0.4; Schrödinger). |
