FIGURE 5.

IsdI-heme reaction products with characteristics of the staphylobilins are produced from either the ascorbic acid or NWMN2274/NADPH reactions. Reaction products were separated from proteins and analyzed by HPLC, and the elution profiles at 465 nm are shown for the ascorbic acid (A) and NWMN2274/NADPH (B) reactions. In both cases there are two major peaks that absorb at 465 nm and are labeled 1 and 2. Optical spectra for peaks 1 (C) and peaks 2 (D) from ascorbic acid (blue lines) and NWMN2274/NADPH (red lines) reactions are shown with wavelengths of maximum absorbance shown for each spectra either above or below the lines.
