Comments

FUNCTION: Catalyzes the reversible reduction of methenyl-H(4)MPT(+) to methylene-H(4)MPT.
CATALYTIC ACTIVITY: H₂ + 5,10-methenyltetrahydromethanopterin = H⁺ + 5,10-methylenetetrahydromethanopterin.
PATHWAY: One-carbon metabolism; methanogenesis from carbone dioxide; 5,10-methylene-H(4)MPT from 5,10-methenyl-H(4)MPT (hydrogen route): step 1/1 .
SIMILARITY: Belongs to the HMD family.
