Figure 3

(A) Ribbon diagram showing the overall structure of Orf6*. Important secondary structural elements discussed in the text include F and G helices (colored in pink), I helix (colored in blue), and Cys loop (colored in red). The heme is shown in yellow sticks and the iron atom as a red sphere. Other secondary structural elements are colored in cyan. (B) Structure-based multiple sequence alignment of the type IV glycopeptide cross-linking cytochrome P450 monooxygenases Orf6* (teicoplanin), StaG (A47934) and Dbv13 (A40926) with those of the type I glycopeptide monooxygenases OxyB and OxyC (both from the vancomycin cluster). Residues that are unique to Orf6* and may be catalytically relevant are shown with a green arrowhead.
