FIG. 8. Comparison of acetate complexes of desaturase (A) and methane monooxygenase hydroxylase (1MMO) (B). Hydrogen bonds to iron ligands are indicated with dotted lines. Glu142 and Asp228 in desaturase, corresponding to Asp143 and Asp242 in MMOH, make hydrogen bonds to the histidine iron ligands.
