ID   1.5.99.15
DE   dihydromethanopterin reductase (acceptor).
CA   5,6,7,8-tetrahydromethanopterin + A = 7,8-dihydromethanopterin + AH2.
CC   -!- This archaeal enzyme catalyzes the last step in the biosynthesis of
CC       tetrahydromethanopterin, a cofactor used in methanogenesis.
CC   -!- The enzyme is characterized from the archaea Methanosarcina mazei and
CC       Methanocaldococcus jannaschii. cf. EC 1.5.1.47.
