Electron transport phosphorylation is the central mechanism for most prokaryotic species to harvest energy released in the respiration of their substrates as ATP. Microorganisms have evolved incredible variations on this principle, most of these we p

During growth of Methanobacterium thermoautotrophicum in a fed-batch fermentor, the cells are confronted with a steady decrease in the concentration of the hydrogen energy supply. In order to investigate how the organism responds to these changes, ce

In Methanosarcina barkeri the transfer of the methyl group from methanol to 2-mercaptoethanesulfonic acid is catalyzed by the concerted action of two methyltransferases. The first one is the corrinoid-containing methanol:5-hydroxybenzimidazolylcobami

Methanol:5-hydroxybenzimidazolylcobamide methyltransferase (MT1) is the first of two enzymes involved in the transmethylation reaction from methanol to 2-mercaptoethanesulfonic acid in Methanosarcina barkeri. MT1 only binds the methyl group of methan

Formylmethanofuran:tetrahydromethanopterin (H4MPT) formyltransferase and 5,10-methenyl-H4MPT cyclohydrolase purified from Methanosarcina barkeri catalyze a formyl group transfer and the hydrolysis of the methenyl function, respectively. The results f

Factor F390 is the 8-OH adenylated form of the deazaflavin coenzyme F420, which is a central electron carrier in methanogenic bacteria. The enzymes catalysing the formation of F390 from ATP and F420 (F390 synthetase) and its hydrolysis into AMP and F

5,10-Methylenetetrahydromethanopterin reductase was purified 22-fold to apparent homogeneity from the methanogenic bacterium Methanobacterium thermoautotrophicum. The enzyme catalyzes the reduction of 5,10-methylene- to 5-methyltetrahydromethanopteri

Methanogenic bacteria comprise a selected group of microorganisms that derive their energy for growth from the hydrogen-dependent reduction of CO2 to methane or the disproportionation of reduced one-carbon compounds and acetate to CO2 and methane. In
