General annotation (Comments)

Function	Catalyzes the reversible reduction of methenyl-H(4)MPT(+) to methylene-H(4)MPT By similarity.
Catalytic activity	5,10-methylenetetrahydromethanopterin + coenzyme F420 = 5,10-methenyltetrahydromethanopterin + reduced coenzyme F420.
Pathway	One-carbon metabolism; methanogenesis from carbone dioxide; 5,10-methylene-H(4)MPT from 5,10-methenyl-H(4)MPT (cofactor F420 route): step 1/1.
Sequence similarities	Belongs to the MTD family.
