biochemistry, a zymogen (/ˈzaɪmədʒən, -moʊ-/), also called a proenzyme (/ˌproʊˈɛnzaɪm/), is an inactive precursor of an enzyme. A zymogen requires a biochemical...

The difference between zymogens and the activated enzymes lies in the fact that the active site for catalysis of the zymogens is distorted. As a result...

purified from human skin (1968), and was recognized to be synthesized as a zymogen. The "cysteine switch" was described in 1990. The MMPs have a common domain...

phenylalanine and tryptophan increase the probability of cleavage. Pepsin's zymogen (proenzyme), pepsinogen, is released by the gastric chief cells in the...

proteins and hormones are synthesized in the form of their precursors - zymogens, proenzymes, and prehormones. These proteins are cleaved to form their...

cells called "chief cells" in its inactive form pepsinogen, which is a zymogen. Pepsinogen is then activated by the stomach acid into its active form...

walls. The cells of each acinus secrete inactive digestive enzymes called zymogens into the small intercalated ducts which they surround. In each acinus,...

in the blood clotting is the initiation of thrombin formation from the zymogen prothrombin. Thromboplastin defines the cascade that leads to the activation...

fibrin is termed fibrinolysis. In humans, the plasmin protein (in the zymogen form of plasminogen) is encoded by the PLG gene. Plasmin is a serine protease...

Factor XI, or plasma thromboplastin antecedent, is the zymogen form of factor XIa, one of the enzymes involved in coagulation. Like many other coagulation...
