Pharmaceutical Enzymes are protein – biological catalysts that speed up chemical reactions in living organisms. These can be used as drugs, which have two important features that distinguish them from all the other types of chemical drugs. First, they bind and act on their targets with great affinity and specificity. And second, they are catalytic in nature converting multiple target molecules to the desired products. These two features make Pharmaceutical Enzymes specific and potent drugs that can accomplish therapeutic biochemistry in the body that small molecules cannot.

Most of these therapeutic enzymes are produced industrially by employing various types of fermentation techniques, using a suitable expression system which includes a microbial strain (bacteria, yeast, fungi, etc), plant or animal cell culture, and genetically engineered organisms. The advancements in the fields of recombinant DNA technology, protein engineering, material science, enzyme immobilization, and nanotechnology has provided an astounding platform for the development of enzymatic drugs that have varied applications in the treatment of a range of diseases.
