FUNCTION: Part of a complex that catalyzes the formation of methyl-coenzyme M and tetrahydromethanopterin from coenzyme M and methyl-tetrahydromethanopterin. This is an energy-conserving, sodium-ion translocating step. MtrH catalyzes the transfer of the methyl group from methyl-tetrahydromethanopterin to the corrinoid prosthetic group of mtrA (By similarity).
CATALYTIC ACTIVITY: 5-methyl-5,6,7,8-tetrahydromethanopterin + 2-mercaptoethanesulfonate = 5,6,7,8-tetrahydromethanopterin + 2-(methylthio)ethanesulfonate.
case <Property:METHANOG>
PATHWAY: One-carbon metabolism; methanogenesis from CO(2); methyl-coenzyme M from 5,10-methylene-5,6,7,8-tetrahydromethanopterin: step 2/2.
end case
SUBUNIT: The complex is composed of 8 subunits; mtrA, mtrB, mtrC, mtrD, mtrE, mtrF, mtrG and mtrH (By similarity).
SIMILARITY: Belongs to the mtrH family.
