Comments [?]

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.
Catalytic activity	RHEA:53492: 5-methyl-5,6,7,8-tetrahydromethanopterin + coenzyme M + 2 Na(+)(in) = 5,6,7,8-tetrahydromethanopterin + methyl-coenzyme M + 2 Na(+)(out) EC 2.1.1.86

case <OC:Methanobacteria> or <OC:Methanococci> or <OC:Methanomicrobia> or <OC:Methanopyri>

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.
Subcellular location	Cell membrane; Multi-pass membrane protein.
Similarity	Belongs to the MtrC family.
