Flavin-containing monooxygenases: new structures from old proteins

A study reports the structures of membrane-bound flavin-containing monooxygenases (FMOs), solved using reconstructed ancestral mammalian FMOs. The models provide a structural basis for these enzymes’ mechanism of action and show how the proteins interact with membranes and how substrates access their active sites.
