Figure 2
Stereoview of water-mediated interactions between Arg40 of IFS (gray surface) and the active site of SPN (green ribbon). Arg40 of IFS is represented as a ball-and-stick model inside the surface in teal color. Residues of SPNct interacting with IFS Arg40 are shown as ball and stick. Purple spheres are water molecules and dotted lines denote hydrogen bonds.  [article HTML]
