Fumarate reductase
Fumarate reductase is the enzyme that converts fumarate to succinate, and is important in microbial metabolism as a part of anaerobic respiration. The catalyzed reaction is: succinate + acceptor ↔ fumarate + reduced acceptor Fumarate reductases can be divided into three classes depending on the electron acceptor: Fumarate reductase (NADH) (EC 1.3.1.6) The enzyme is monomeric and soluble, and can reduce fumarate independently from the electron transport chain.
