ENZYME entry: EC 7.2.1.4

Accepted Name

tetrahydromethanopterin S-methyltransferase

Alternative Name(s)

N(5)-methyltetrahydromethanopterin--coenzyme M methyltransferase

tetrahydromethanopterin methyltransferase

Reaction catalysed

5-methyl-5,6,7,8-tetrahydromethanopterin + coenzyme M + 2 Na(+)(in) = 5,6,7,8-tetrahydromethanopterin + methyl-coenzyme M + 2 Na(+)(out)

Comment(s)

Involved in the formation of methane from CO in methanogenic archaea.
The reaction involves the export of one or two sodium ions.
The enzyme from the archaeon Methanobacterium thermoautotrophicum is a membrane-associated multienzyme complex composed of eight different subunits, and contains a 5'-hydroxybenzimidazolyl-cobamide cofactor, to which the methyl group is attached during the transfer.
A soluble enzyme that is induced by the presence of CO has been reported as well.
Formerly EC 2.1.1.86.
