Abstract

The ability of hydrolytic products of coenzyme F420 to substitute for F420 in the hydrogenase and nicotinamide adenine dinucleotide phosphate-liniked hydrogenase systems of Methanobacterium strain M.o.H. was kinetically determined. The nicotinamide adenine dinucleotide phosphate-linked hydrogenase system was employed to quantitate the levels of F420 in a number of methanogenic bacteria as well as in some nonmethanogens. Methanobacterium ruminantium and Methanosarcina barkeri contained low levels of F420, whereas other methanogens tested contained high levels (100 to 400 mg/kg of cells). F420 from six of the seven methanogens was tested by thin-layer electrophoresis and was found to be electrophoretically identical to that purified from Methanobacterium strain M.o.H. The only exception was M. barkeri, which contained a more electronegative derivative of F420. Acetobacterium woodii, Escherichia coli, and yeast extract contained no compounds able to substitute for F420 in the nicotinamide adenine dinucleotide phosphate-linked hydrogenase system.
