Figure 8. Stimulation by A. suum cytochrome b₅ of nematode cytochrome b₅ reductase-catalysed reduction of nematode body-wall metmyoglobin.

(A) Difference spectra obtained by repeated scanning show the time course of metmyoglobin reduction in the presence of 0.384 μM cytochrome b₅. Time-dependent increase in absorptions at 543 and 578 nm was observed during 13 cycle scanning. (B) Dose-dependent relationship between reduction rate and concentration of added cytochrome b₅. Experimental details are described in the Experimental section.
