pubmed:abstractText |
Hydrogen gas production was observed to occur during ATP-driven H+/K+ exchange in anaerobically grown E. coli. Neither process was found in aerobically grown cells or anaerobic cells grown on nitrate medium or when the osmotic pressure was decreased or K+ removed, or finally when DCCD, arsenate or CCCP was applied. Dithiothreitol restored the process even in the presence of CCCP but not in other cases of inhibition. A model of a multienzyme transport super-complex is proposed. The supercomplex consists of three genetically independent mechanisms: F0F1 H+-ATPase to provide energy, the K+-transporting Trk system as energy sink and formate-hydrogen lyase as donor of reducing equivalents. Within this supercomplex direct transduction of energy is accomplished via oxidation of 2 SH to S-S.
