Figure 4
Structural differences in the catalytic triad. (a) EcTae4 and StTae4 have a conserved catalytic active center containing the catalytic residues (Cys–His–Asp), which have a similar arrangement to the catalytic triad of papain (PDB entry 1bp4; LaLonde et al., 1998BB6). (b) SmTae4 and AtTae4 have the conserved catalytic residues (Cys–His–Asp), but the third aspartic acid in the catalytic triad has a distinct spatial arrangement.
