Before revision:  Our measurements based on using four independent techniques, static light scattering, dynamic light scattering (DLS), size-exclusion chromatography (SEC), and fluorescence correlation spectroscopy (FCS) , lead to this conclusion for the enzymes urease (emphasized in the main text ), and hexokinase and acetylcholinesterase (data shown in the supplementary material), each of which catalyzes different reactions.
