Members of this family adopt a alpha-beta structure, with a core comprising three alpha/beta/alpha layers, in which each sheet contains four strands. They are predominantly found in prokaryotic methylene-tetrahydromethanopterin dehydrogenase, which catalyses the dehydrogenation of methylene-tetrahydromethanopterin and the reversible dehydrogenation of methylene-H(4)F [1].
