| Other name(s): |
N5,N10-methylenetetrahydromethanopterin dehydrogenase; 5,10-methylenetetrahydromethanopterin dehydrogenase |
| Systematic name: |
5,10-methylenetetrahydromethanopterin:coenzyme-F420 oxidoreductase |
| Comments: |
Coenzyme F420 is a 7,8-didemethyl-8-hydroxy-5-deazariboflavin derivative; methanopterin is a pterin analogue. The enzyme is involved in the formation of methane from CO2 in the methanogen Methanothermobacter thermautotrophicus. |
