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 | 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=7.2.1.4; |
| 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; Single-pass membrane protein. |
| SIMILARITY | Belongs to the MtrG family. |
