title: Schistosoma mansoni: ferredoxin-NADP(H) oxidoreductase and the metabolism of reactive oxygen species.
abstract: Mitochondrial-type ferredoxin-NADP(H) oxidoreductases (FNR) catalyze the electron transport between NADPH and substrates such as ferredoxins. Even though enzymes belonging to this family are present in several organisms, including prokaryotes, their biological function is not clearly understood. In a previous work, we reported the existence of a mitochondrial-type FNR in the trematode Schistosoma mansoni (SmFNR). This enzyme conferred tolerance to oxidative stress conditions when tested in an heterologous system. In this work, we demonstrate that the SmFNR can be imported to mitochondria in mammal cells and show that its expression is induced in parasite cultures by reactive oxygen species (ROS). The results reported herein give further support to the involvement of SmFNR in ROS metabolism.
