Emerging pollutants in the aquatic environment from pharmaceutical and personal care products (PPCPs) attract much attention due to their environmental risk and toxicological properties, posing a threat to human health and safety. In this study, we fulfilled the direct and efficient degradation of PPCPs (i.e. diclofenac sodium, 2-mercap-tobenzothiazole, paracetamol, and furosemide) using engineered H2O2-dependent heme enzymes based on myoglobin (Mb) with high peroxidase activity. Especially, the triple mutant F43Y/P88W/F138W Mb could efficiently degrade diclofenac sodium, 2-mercaptobenzothiazo...
