Comparison of biphenyl 2,3-dioxygenase active site to other Rieske oxygenaes. Comparison of the active sites of NDO-O9816-4 and BPDO-ORHA1 with BPDO-OB1. NDO-O9816-4 (top) and BPDO-ORHA1 (bottom) active site residues are shown as smooth grey lines and the active site iron is shown as a grey sphere. BPDO-OB1 is aligned and overlaid in each of the images. Residues that coordinate the mononuclear iron are shown as red ball and stick models, while residues that form the active site pocket are shown as green ball and stick models. The mononuclear iron for BPDO-OB1 is shown as a rust colored sphere. Residues are labeled using numbering from BPDO-OB1. Left and center images are wall-eyed stereo, center and right images are cross-eyed stereo.
