BACKGROUND: Pseudomonas sp. NCIB 9816-4 utilizes a multicomponent enzyme system to oxidize naphthalene to (+)-cis-(1R,2S)-dihydroxy-1,2-dihydronaphthalene. The enzyme component catalyzing this reaction, naphthalene 1,2-dioxygenase (NDO), belongs to a family of aromatic-ring-hydroxylating dioxygenases that oxidize aromatic hydrocarbons and related compounds to cis-arene diols. These enzymes utilize a mononuclear non-heme iron center to catalyze the addition of dioxygen to their respective substrates. The present study was conducted to provide essential structural information necessary for elucidating the mechanism of action of NDO. RESULTS: The three-dimensional structure of NDO has been determined at 2.25 A resolution. The molecule is an alpha 3 beta 3 hexamer. The center and a catalytic domain that has a novel fold dominated by an antiparallel nine-stranded beta-pleated sheet against which helices pack. The active site contains a non-heme ferrous ion coordinated by His208, His213, Asp362 (bidentate) and a water molecule. Asn201 is positioned further away, 3.75 A, at center, one iron is coordinated by Cys81 and Cys101 and the other by His83 and His104. CONCLUSIONS: The domain structure and iron coordination of the Rieske domain is very similar to that of the cytochrome bc1 domain. The active-site iron center of one of the alpha subunits is directly connected by hydrogen bonds through a center in a neighboring alpha subunit. This is likely to be the main route for electron transfer.

Figure 1. Stereo omit F[o] -F[c] electron-density map at 2.25 resolution of crystal form II (3 rms). The map is for the region around the catalytic iron center with the ligands His208, His213 and Asp362. The iron ion was not present in the preceding refinement (close to the final stages of refinement) and the ligands were refined as alanine residues.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
