Structural and functional studies of ferredoxin and oxygenase components of 3-nitrotoluene dioxygenase from Diaphorobacter sp. strain DS2
Fig 2
Proposed electron transfer pathway between 3NTDO-FDS2 and 3NTDO-ODS2.
(A) Ferredoxin is shown in brown color at the top of 3NTDO-ODS2; Iron and sulphur are shown in magenta and yellow. (B) A line is drawn from Rieske center of 3NTDO-FDS2 to the mononuclear iron of 3NTDO-ODS2 through the Rieske cluster of 3NTDO-ODS2. (C) Proposed electron transfer pathway from Rieske cluster of ferredoxin to active site mononuclear iron of oxygenase of NDO is plotted in ball and stick model, the residues of chain A and chain C of oxygenase are shown in green and cyan color.
