CC   -!- FUNCTION: Part of a complex that catalyzes the formation of methyl-
CC       coenzyme M and tetrahydromethanopterin from coenzyme M and methyl-
CC       tetrahydromethanopterin. This is an energy-conserving, sodium-ion
CC       translocating step. MtrH catalyzes the transfer of the methyl group
CC       from methyl-tetrahydromethanopterin to the corrinoid prosthetic group
CC       of MtrA.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=5-methyl-5,6,7,8-tetrahydromethanopterin + coenzyme M + 2
CC         Na(+)(in) = 5,6,7,8-tetrahydromethanopterin + methyl-coenzyme M + 2
CC         Na(+)(out); Xref=Rhea:RHEA:53492, ChEBI:CHEBI:29101,

case <OC:Methanobacteria> or <OC:Methanococci> or <OC:Methanomicrobia> or <OC:Methanopyri>
CC   -!- PATHWAY: One-carbon metabolism; methanogenesis from CO(2); methyl-
CC       coenzyme M from 5,10-methylene-5,6,7,8-tetrahydromethanopterin: step
CC       2/2.
end case
CC   -!- SUBUNIT: The complex is composed of 8 subunits; MtrA, MtrB, MtrC, MtrD,
CC       MtrE, MtrF, MtrG and MtrH.
CC   -!- SIMILARITY: Belongs to the MtrH family.
