Gene name	Name=mtrA;

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;
COFACTOR	Name=5-hydroxybenzimidazolylcob(I)amide; Xref=ChEBI:CHEBI:60494; Note=Binds 1 5-hydroxybenzimidazolylcobamide group.;
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 MtrA family.
