Figure 5From: Structural insight into the substrate- and dioxygen-binding manner in the catalytic cycle of rieske nonheme iron oxygenase system, carbazole 1,9a-dioxygenaseWater molecule proposed as a proton donor for the peroxide. The water molecule had hydrogen-bonds to Glu284, Tyr296, and Arg337, which were conserved perfectly in all reported CARDO-Os.Back to article page
