The factor that makes enzyme biocatalysts for organic synthesis both fascinating and challenging from a scientific standpoint is the field's higher interdisciplinarity, and which necessitates expertise from a wide range of disciplines, including microbiology, organic synthesis, molecular biology, genetics, and reaction engineering. Enzymes can now carry out a wide variety of organic reactions, including hydrolytic reactions, redox reactions, and C-C bond formations, with higher performance. Enzyme catalysis has also evolved into a widely used manufacturing technology in the chemical industry, especially in the fields of fine organic chemicals and pharmaceuticals. More advances in molecular modeling for enzyme-catalysis syntheses are expected, allowing for a greater number of biocatalytic techniques based on the enzymes that have been optimized or engineered by rationalized protein engineering. The organic chemists mostly have successfully used these custom-made biocatalysts (the isolated pure enzymes, the recombinant genetically modified microorganisms, also known as the designer cells), an important milestone in the enzyme catalysis process in organic synthesis is into generally accepted synthetic technology for academia as well as industries.
