ENZYME entry: EC 1.3.4.1

Accepted Name
Fumarate reductase (CoM/CoB).
Alternative Name(s)
Thiol:fumarate reductase.
Reaction catalysed
Fumarate + CoM + CoB <=> succinate + CoM-S-S-CoB
Comment(s)
  • The enzyme, isolated from the archaeon Methanobacterium thermoautotrophicum, is very oxygen sensitive.
  • It cannot use reduced flavins, reduced coenzyme F420, or NAD(P)H as an electron donor.

  • Formerly EC 1.3.98.2.
