Which among the following is highly specific? Correct Answer Thrombin

Thrombin is a highly specific protein. It reacts only with the protein fibrinogen. It is a part of a very delicate blood-clotting mechanism and thus must act only on one compound to maintain the proper functioning of the system. Pepsin, DNase, and chymotrypsin are not highly specific enzymes.
