Figure 3

(A) A ribbon drawing of the C2’H homology model colored (cyan) superimposed on the F6’H1 crystal structure (tan). The sodium ion occupying the iron binding site is colored magenta. Regions showing the greatest structural deviations from the F6’H1 crystal structure are highlighted in red. (B) A ribbon drawing of a theoretical model of the C2’H 2OG-FeII_OXY domain showing active site components. The active site iron is colored orange. The 4-coumaroyl group of the 4-coumaroyl–CoA substrate (upper left) and 2OG (lower right) are depicted using ball and stick representations. Position C2 of the 4-coumaroyl group, the site of enzymatic attack is highlighted in magenta.
