... expressions for calculating the apparent equilibrium constant ( K ′) of the creatine kinase, adenylate kinase and ATP hydrolysis reactions in terms of K ref and the appropriate acid-dissociation and magnesium-binding constants. We have calculated K ref for each reaction and demonstrated how K ′ can...

... of the CF 1 subunits. The e subunit is also an inhibitor of the ATPase activity of E. coli F 1 and has been shown to interact strongly with γ ( Dunn, 1982 ). The E. coli ATP synthase can operate as an H + -ATPase in vivo . For example, when respiratory chain activity is low, ATP hydrolysis...
