Understanding the dynamics of complex in-situ enzyme-catalyzed reactions undergoing mechanical stress

Abstract

Understanding the diversity in the enzymatic mechanism have utmost importance as it can temporally control the catalytic efficiency. Recent literature suggests that by influencing mechanical properties of hybrid materials, the catalytic efficiency of the enzymatic reactions can be altered significantly. Here, taking a computational and experimental approach, we have dig out the fate of the kinetics of enzyme reaction systems exhibiting relatively complex mechanism than usual Michaelis Menten kinetics involving multiple substrate/enzyme/enzyme-substrate complex. We have developed a numerical recipe improvising stochastic reaction-diffusion approach to explore the role of mechanical stress like compression-decompression cycle (C-D) on modulating the output of enzymatic reaction. The proposed methodology can be used as a theoretical tool to understand how to enhance the catalytic activity and setup appropriate reaction conditions by efficiently using the catalytic cycles. Hence, our methodology will be crucial to identify the most effective strategy to efficiently convert substrate into product in this type of mechanoresponsive materials, which will enable future development of cost-effective biomaterials. In future, the insights gained from this work may find enormous application in drug delivery, tissue engineering, bio-sensing and bio-catalysis.
