Relationship between formate hydrogen lyase and proton-potassium pump under heterolactic fermentation in Escherichia coli: functional multienzyme associations in the cell membrane.

Abstract excerpt

Anaerobically grown glucose-fermenting E. coli cells produce molecular hydrogen, acidify the medium and uptake potassium ions. It was shown that the H2 release and the proton-potassium exchange with the fixed (2H+/K+) stoichiometry of the initial DCC-sensitive fluxes were lost in mutants with the deleted fdhF gene or the hycA-H operon responsible for the biosynthesis of formate dehydrogenase H (FDH,H) or...
