Parameter values vary widely between enzymes: The constant (catalytic efficiency) is a measure of how efficiently an enzyme converts a substrate into product. Diffusion limited enzymes, such as fumarase, work at the theoretical upper limit of 10 – 10 M s , limited by diffusion of substrate into the active site. Michaelis–Menten kinetics have also been applied to a variety of topics outside of biochemical r… WebEngineering Enzymes Saturation kinetics is a tool that can be utilized in enzyme engineering to change enzymes so that they are more suitable for a given purpose.
