Fumarate reductase

• Fumarate reductase
• :The membrane-bound enzyme covalently linked to flavin cofactors, which is composed of 3 or 4 subunits, transfers electrons from a quinol to fumarate. This class of enzyme is thus involved in the production of ATP by oxidative phosphorylation.
• Fumarate reductase
• :The enzyme is monomeric and soluble, and can reduce fumarate independently from the electron transport chain. Fumarate reductase is absent from all mammalian cells.
