additional information Ascaris suum complex II of adult organism muscle exhibits high fumarate reductase activity and plays a key role in anaerobic electron-transport during adaptation to their microaerobic habitat, in contrast larval complex II shows a much lower fumarate reductase activity than the adult enzyme and functions as succinate dehydrogenase in aerobic respiration ?

additional information the fumarate reductase of the parasitic adult and the succinate dehydrogenase of free-living larvae share a common iron-sulfur subunit, at least the flavoprotein subunit and the small subunit of cytochrome b of the larval complex II differ from those of adult Ascaris suum
additional information the enzyme contains iron-sulfur centers Ascaris suum
