Escherichia coli proton-translocating F0F1-ATP synthase and its association with solute secondary transporters and/or enzymes of anaerobic oxidation-reduction under fermentation.
The Escherichia coli proton-translocating F0F1-ATP synthase has a priority in H+ circulation through the membrane in maintaining proton-motive force in the context of ATP synthesis and hydrolysis. Recent advances in the study of this complex under fermentative growth have led to hypothesis that, in the absence of oxidative phosphorylation, F0F1 is implicated as an essential part of H+ movement and ATP hydrolysis, associated with solute secondary transporters and/or enzymes of anaerobic oxidation-reduction. These associations can result from a protein-protein interaction by dithiol-disulfide interchange. In such associations F0F1 has novel functions in bacterial cell physiology.
