Methanosphaera stadtmanae reduces methanol to CH4 in a similar way as Methanosarcina barkeri. Low activities of 5,10-methylenetetrahydromethanopterin dehydrogenase (MTDH) and reductase (MTR) were found. From studies on formaldehyde oxidation and reduction it was concluded that most likely the inability to reduce CO2 to CH4 was due to the lack of an active(More)
Cell extracts of Methanosarcina barkeri converted coenzyme F420 in an ATP-dependent reaction to the adenylylated derivative factor 390. Although it was reported previously (L. M. Gloss and R. P. Hausinger, BioFactors 1:237-240, 1988) that whole cells were unable to perform this conversion, we observed the conversion in 7 of 11 extracts, all of which were(More)
