Augmenting off-the-shelf enzyme activities by multiple folds with a supramolecular complex additive
Year: 2025
Type: article
Abstract: Enzymes are commonly used industrial reagents, and enhancement of their activity is often pursued to make them more attractive reagents. Here, we discovered that simply adding two chemical additives can augment many enzyme activities above their native range in their usual reaction buffers, leading to around 1.5–40 times higher reaction rates and product yields. The augmenting system comprises a zwitterionic bile salt derived detergent and a per-aminated cyclodextrin, forming a dynamic supramolecular system for in perpetuum protein folding. Our discovery provides an additional dimension to augment protein functions independent of other parameters and suggests certain solutes may provide near-universal modulation of protein functions beyond the commonly considered electrolytes and solvents. • Simply adding two chemicals can augment enzyme activity by 1.5-40x. • The augmentation broadly applies to various enzymes and reaction conditions. • Our approach represents a new approach to increase enzyme activity.
