5,6,7,8-tetrahydromethanopterin + NAD(+) = 7,8-dihydromethanopterin + NADH + H(+)
5,6,7,8-tetrahydromethanopterin + nad(+) = 7,8-dihydromethanopterin + nadh + h(+)
5,6,7,8-tetrahydromethanopterin + NAD(+) = 7,8-dihydromethanopterin + NADH + H(+)
5,6,7,8-tetrahydromethanopterin + nad(+) = 7,8-dihydromethanopterin + nadh + h(+)
