RHO enzyme reconstitution study showing ETC compatibility with the NidAB and NidA3B3 systems

	Relative yield of dihydrodiol formation (%)b
Type V ETCa	NidABc	NidA3B3d
PhtAcAd	905 (100)	2,875 (15)
PhdCD	129 (14)	19,163 (100)

^a PhtAcAd from M. vanbaalenii PYR-1 (26) and PhdCD from Nocardioides sp. strain KP7 (27).

^b Formation of dihydrodiol metabolites was measured based on the HPLC peak area (mAU × s). Representative results are shown for each of the enzyme reconstitution assays.

^cFormation of pyrene cis-4,5-dihydrodiol.

^dFormation of fluoranthene cis-2,3-dihydrodiol.
