Function
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
- 5-methyl-5,6,7,8-tetrahydromethanopterin + coenzyme M + 2 Na+(in) = 5,6,7,8-tetrahydromethanopterin + methyl-coenzyme M + 2 Na+(out)
Pathway
One-carbon metabolism; methanogenesis from CO2; methyl-coenzyme M from 5,10-methylene-5,6,7,8-tetrahydromethanopterin: step 2/2.
