Switching between degradation and polymerization reactions on demand. (a and b) Buffer exchange via flow was used to reverse the directionality: 10 mM ADP followed by 10 mM Pi (a); 10 mM ADP followed by 1 mM Pi (b). Linear fits to the two reaction segments are also shown. (c) Histogram of the ratio between speeds of degradation at 10 mM Pi and polymerization at 10 mM ADP and a Gaussian fit. (d) Histogram of the ratio between speeds of degradation at 1 mM Pi and polymerization at 10 mM ADP and a Gaussian fit.
