Abstract Click to copy section linkSection link copied! Oxidoreductases are basic enzymes that catalyze redox reactions within cells. Naturally occurring oxidoreductases have high catalytic activity and substrate specificity, playing critical roles in bioenergy metabolism, the food industry, and biotechnology. However, limitations, such as high cost, low stability, and poor tolerance to reaction conditions, restrict their practical applications.
