Compound as reactive (2)
2 a reduced electron donor + 7,8-dihydromethanopterin → 2 an oxidized electron donor + 2 H+ + tetrahydromethanopterin
NAD(P)+ + tetrahydromethanopterin ← NAD(P)H + 7,8-dihydromethanopterin + H+
Compound as product (2)
2 S-adenosyl-L-methionine + demethylated 7,8-dihydromethanopterin → 2 S-adenosyl-L-homocysteine + 7,8-dihydromethanopterin
[1-(2-amino-7-methyl-4-oxo-7,8-dihydro-3H-pteridin-6-yl)]ethyl-(4-aminophenyl)-1-deoxy-5-[1-α -D- ribofuranosyl triphosphate]-D-ribitol + (S)-2-hydroxyglutarate → 7,8-dihydromethanopterin + diphosphate
Reversible reaction (1)
an oxidized electron donor + tetrahydromethanopterin ↔ 7,8-dihydromethanopterin + a reduced electron donor
