Abstract

With the ever-increasing rates of catalysis shown by catalytic amyloids, the use of faster characterization techniques is required for proper kinetic studies. The same is true for inherently fast chemical reactions. Carbon dioxide hydration is of significant interest to the field of enzyme design, given both carbonic anhydrases’ status as a “perfect enzyme” and the central role carbonic anhydrase plays in the respiration and existence of all carbon-based life. Carbon dioxide is an underexplored hydrolysis substrate within the literature, and a lack of a direct spectroscopic marker for reaction monitoring can make studies more complex and require specialist equipment. Within this article we present a method for measuring the carbon dioxide hydration activity of amyloid fibrils.
