Function

BPHA1_RHOJR Part of the oxygenase component of the biphenyl dioxygenase system that catalyzes the stereospecific dihydroxylation of the aromatic ring of biphenyl, yielding a dihydrodiol compound. Is essential for biphenyl degradation and growth of Rhodococcus sp. strain RHA1 on biphenyl as the sole source of carbon and energy. Can also use naphtalene and 4-chlorobiphenyl (4-CB) as substrates, as well as some polychlorinated biphenyls (PCB) such as 2,2'-dichlorobiphenyl, 2,3-dichlorobiphenyl and 2,5,2'-trichlorobiphenyl. Exhibits weak activity toward dibenzofuran and dibenzo-p-dioxin. Electrons are transferred from NADH to the [2Fe-2S] cluster in BphA1 via FAD of BphA4 and [2Fe-2S] cluster of BphA3.^[1] ^[2]

Publication Abstract from PubMed

Biphenyl dioxygenase is the enzyme that catalyzes the stereospecific dioxygenation of the aromatic ring. This enzyme has attracted the attention of researchers due to its ability to oxidize polychlorinated biphenyls, which is one of the serious environmental contaminants. We determined the crystal structure of the terminal oxygenase component of the biphenyl dioxygenase (BphA1A2) derived from Rhodococcus strain sp. RHA1 in substrate-free and complex forms. These crystal structures revealed that the substrate-binding pocket makes significant conformational changes upon substrate binding to accommodate the substrate into the pocket. Our analysis of the crystal structures suggested that the residues in the substrate-binding pocket can be classified into three groups, which, respectively, seem to be responsible for the catalytic reaction, the orientation/conformation of the substrate, and the conformational changes of the substrate-binding pocket. The cooperative actions of residues in the three groups seem to determine the substrate specificity of the enzyme.
