Figure 7: Binding pose of the PTX03 in TS domain. The 2D (left side with white background) and 3D (right side with black background) view of PTX03 docked in TS domain. In 2D, dotted arrows are showing potential hydrogen bonds with Arg345, His510, Ser524 and His551. The Arg345 is also showing cation-π interaction with PTX03. In 3D view the PTX03 is in green color while the TS domain is in element style.
