Figure 3. Structural positions of the identified amino acids that reduced the shutoff activity of PA-X.

Figure 3.

The identified amino acids are mapped onto a ribbon diagram of the structure of the N-terminal region of PA (2W69). Amino acid residues that are important for the endonuclease activity of PA are shown in magenta. Identified amino acid residues that locate near the endonuclease active site are shown in cyan. Other identified amino acids are shown in green.
