Why might the atpS mutant grow so slowly? In order to answer this, you need to consider the following pieces of information:
(1) ADP + Pi > ATP ∆G’¡ = +52 kJ/mol
(2) Under physiological conditions in the bacterium, this reaction actually has ∆G = +67 kJ/mol.
(3) The free energy change for a proton to re-enter the cytosol will be related to the pH gradient (∆pH) and the transmembrane electric field (ψ) by this relationship:
∆G = -2.3 RT ∆pH + F∆ψ (R = 8.315 J mol-1 K-1; T = 298K; F = 96.5 kJ mol-1 V-1)
(4) In the case of M. wanabi, Typically, ∆ψ = -100 mV.
(5) The environment in which M. wanabi grows is close to neutral (usually pH = 6) and somewhat buffered with weak organic acids.
Calculate what the minimal ∆pH would have to be, in order to support ATP synthesis, for the different Fo ring sizes. Does this explain why the mutant grew slowly and the partial revertant grew better? Explain.
