Comments [?]

FUNCTIONPart 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.
CATALYTIC ACTIVITY Reaction=5-methyl-5,6,7,8-tetrahydromethanopterin + coenzyme M + 2 Na(+)(in) = 5,6,7,8-tetrahydromethanopterin + methyl-coenzyme M + 2 Na(+)(out); Xref=Rhea:RHEA:53492, ChEBI:CHEBI:29101, ChEBI:CHEBI:58103, ChEBI:CHEBI:58116, ChEBI:CHEBI:58286, ChEBI:CHEBI:58319; EC=;
case <OC:Methanobacteria> or <OC:Methanococci> or <OC:Methanomicrobia> or <OC:Methanopyri>
PATHWAYOne-carbon metabolism; methanogenesis from CO(2); methyl- coenzyme M from 5,10-methylene-5,6,7,8-tetrahydromethanopterin: step 2/2.
end case
SUBUNITThe complex is composed of 8 subunits; MtrA, MtrB, MtrC, MtrD, MtrE, MtrF, MtrG and MtrH.
SUBCELLULAR LOCATIONCell membrane; Multi-pass membrane protein.
SIMILARITYBelongs to the MtrE family.
