Comments
This enzyme belongs to a large family of bacterial Rieske non-heme iron oxygenases. This enzyme is a part of naphthalene 1,2-dioxygenase system (NDOS).
Although NADH and NAD+ are included as a substrate and a product, respectively, they do not interact directly with this enzyme. According to the literature [4], [7], [14] and [18], the reaction proceeds as follows:
(#) Ferredoxin-NAD+ reductase (cf. D00071 in EzCatDB) of NDOS catalyzes electron transfer from NADH to Ferredoxin of NDOS.
(A) Electron transfer from Ferredoxin to the FE2S2 (Iron-sulfur) of the oxidized form of this enzyme.
(A1) Indirect transfer through Trp211 from the adjacent alpha-subunit and Val100, to Cys101, which is bound to FE2S2 (see [4]).
(B) Electron transfer from the FE2S2 to the mononuclear iron center of the adjacent subunit of this enzyme.
(B1) Indirect transfer through His104 bound to the FE2S2, the sidechain of Asp205 from the adjacent alpha-subunit, and His208 bound to the mononuclear iron center from the adjacent alpha-subunit (see [4] and [7]).
(C) Oxygenation of naphthalene at the mononuclear iron center.
