tetramer | determined by high resolution clear-native electrophoresis and Western blot analysis. Enzyme consists of four subunits: a flavoprotein subunit (Fp, SDH1) and an iron-sulphur subunit (Ip, SDH2) form a soluble heterodimer, which binds to a membrane anchor b-type cytochrome (SDH3)/CybS (SDH4) heterodimer | Plasmodium yoelii yoelii |
