Enzymes catalyze chemical transformations with outstanding stereo- and regio-specificities, but many enzymes are limited by their long reaction times. Here, we describe a general method to accelerate enzymes using pressure waves contained within thin films. Each enzyme responds best to specific frequencies of pressure waves, and we report acceleration landscapes for each protein. A vortex fluidic device introduces pressure waves that drive increased rate constants (kcat) and enzymatic efficiency (kcat/Km). Four enzymes displayed an average seven-fold acceleration with deoxyribose-5-phosphate aldolase (DERA) achieving an average 15-fold enhancement through this approach. In solving a common problem in enzyme catalysis, we have uncovered a powerful, generalizable tool for enzyme acceleration. This research provides new insights into previously uncontrolled factors affecting enzyme function. Enzymes – They’re Picking Up Good Vibrations: A simple, generalizable approach to accelerate enzymes through the use of pressure waves in thin films has been developed. Each enzyme responds best to specific vibrations uncovering a previously unappreciated aspect of biocatalysis.
