Function

SDHA1_ASCSU Flavoprotein (Fp) subunit of the mitochondrial electron transport chain complex II which, together with the iron-sulfur protein (Ip) subunit forms the catalytic core of the complex (PubMed:12742584, PubMed:17933581, PubMed:2843227, PubMed:7739664, PubMed:7822332, PubMed:8435436). During the parasitic larvae and adult stages, which occur in an anaerobic environment, acts as a fumarate reductase by transferring electrons from rhodoquinol to fumarate (PubMed:12742584, PubMed:17933581, PubMed:2843227, PubMed:7739664, PubMed:7822332, PubMed:8435436).[1] [2] [3] [4] [5] [6]
