Comments "...[researchers] report the application of the viscosity variation method to the reaction catalyzed by triosephosphate isomerase, an enzyme that has a value of kcat/Kmin the thermodynamically downhill direction of 4×10^8M^-1×s^-1 (primary source) and seems a likely candidate for a reaction that proceeds at the diffusion limit."
