NiceZyme View of ENZYME: EC 2.8.4.1

Accepted Name
Coenzyme-B sulfoethylthiotransferase.
Alternative Name(s)
Methyl coenzyme M reductase.
Methyl-CoM reductase.
Reaction catalysed
2-(methylthio)ethanesulfonate (methyl-CoM) + N-(7-mercaptoheptanoyl)threonine 3-O-phosphate (coenzyme B) <=> CoM-S-S-CoB + methane
Cofactor(s)
Coenzyme F430.
Comment(s)
  • Highly specific for coenzyme B with a heptanoyl chain; ethyl CoM and difluoromethyl CoM are poor substrates.
  • The sulfide sulfur can be replaced by selenium but not by oxygen.
