Protein attributes

Sequence length	266 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Reduction of methyl-coenzyme M (2-(methylthio) ethanesulfonic acid) with 7-mercaptoheptanoylthreonine phosphate to methane and an heterodisulfide By similarity.
Catalytic activity	2-(methylthio)ethanesulfonate (methyl-CoM) + N-(7-mercaptoheptanoyl)threonine 3-O-phosphate (coenzyme B) = CoM-S-S-CoB + methane.
Cofactor	Binds 2 coenzyme F430 noncovalently per hexamer. Coenzyme F430 is a yellow nickel porphinoid By similarity.
Pathway	One-carbon metabolism; methyl-coenzyme M reduction; methane from methyl-coenzyme M: step 1/1.
Subunit structure	Hexamer of two alpha, two beta, and two gamma chains By similarity.
