Fig. 3

Active site of N225D trichodiene synthase complexed with Mg2+3-PPi. (a) Simulated annealing omit maps of PPi and metal ions are shown in cyan (7.5Å) and maroon (6.8σ), respectively. Metal ion coordination and hydrogen bond interactions are shown in black and gray, respectively. (b) Superposition of the active sites of PPi-bound wild-type (purple) and N225D (magenta) trichodiene synthases. Note that the metal ion coordination and hydrogen bond interactions are similar in the wild-type (purple) and N225D trichodiene synthases (black and gray).
