Figure 3
AmsI active site. Residues 10–16 of the P-loop, the sulfate (SO4) and the water molecule (H2O; HOH2017) in the active site are shown in ball-and-stick representation. Atoms are coloured as follows: carbon, grey; oxygen, red; nitrogen, blue; sulfur, yellow; hydrogen, white. The water H atoms are included in the model. Hydrogen bonds are represented as dotted yellow lines. This image was prepared with the PyMOL molecular-graphics system (v.1.7; Schrödinger). |
