Interpro abstract (IPR003814): | This entry represents a domain found in subunit E of formylmethanofuran dehydrogenase (FmdE). It appears to be related to the Tubulin/FtsZ 2-layer sandwich domain. Formylmethanofuran dehydrogenases ( EC 1.2.7.12 ), found in methanogenic archaea, are molybdenum or tungsten iron-sulphur proteins containing a pterin dinucleotide cofactor. Formylmethanofuran dehydrogenase catalyses the reversible reduction of CO 2 and methanofuran via N-carboxymethanofuran (carbamate) to N-formylmethanofuran, the first and second steps in methanogenesis from CO 2 [ (PUBMED:8575452) ]. There are two isoenzymes of formylmethanofuran dehydrogenase: a tungsten-containing isoenzyme (Fwd) and a molybdenum-containing isoenzyme (Fmd). The tungsten isoenzyme is constitutively transcribed, whereas transcription of the molybdenum operon is induced by molybdate [ (PUBMED:9818358) ]. |
