Enzyme modification technology can improve the catalytic activity and stability of enzymes, making them more suitable for use in the medical testing industry. This article focuses on seven molecular chemical modification methods, including small molecule chemical modification, polymer modification, enzyme cross-linking modification, and cofactor modification, as well as three genetic engineering modification methods, including directed evolution and site-specific mutation modification. The development prospects of enzyme modification technology are also discussed.
