O-Cresolphthalein

O-Cresolphthalein (ortho-Cresolphthalein), a type of biocatalyst, plays a crucial role as a key enzyme in emerging biocatalyst technology. Enzyme engineering focuses on improving enzyme reaction kinetics, substrate selectivity, and activity under extreme conditions (such as low or high pH) . By incorporating stimulus-responsive modifications into these enzymes, dynamic activity control is also achievable.
