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. {ECO:0000255|HAMAP-Rule:MF_01099}.
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,
CC ChEBI:CHEBI:58103, ChEBI:CHEBI:58116, ChEBI:CHEBI:58286,
CC ChEBI:CHEBI:58319; EC=2.1.1.86; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01099};
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. {ECO:0000255|HAMAP-Rule:MF_01099}.
CC -!- SUBUNIT: The complex is composed of 8 subunits; MtrA, MtrB, MtrC, MtrD,
CC MtrE, MtrF, MtrG and MtrH. {ECO:0000255|HAMAP-Rule:MF_01099}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_01099};
CC Single-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_01099}.
CC -!- SIMILARITY: Belongs to the MtrF family. {ECO:0000255|HAMAP-
CC Rule:MF_01099}.
