After activation of the zymogen via Thrombin to its active enzyme form, Factor XIIIa is responsible for catalyzing the formation of covalent bridges between fibrin units to increase the elasticity of the clot network. The resulting cross-linked fibrin is very insoluble and resistant to lysis. Enzyme Research Laboratories offers the zymogen form of Human Factor XIII (a2b2). More Info. Human.
A zymogen (or proenzyme) is an inactive enzyme precursor. A zymogen requires a biochemical change (such as a hydrolysis reaction revealing the active site, or changing the configuration to reveal the active site) for it to become an active enzyme. The biochemical change usually occurs in a lysosome where a specific part of the precursor enzyme is cleaved in order to activate it. The.

The lack of enzymatic activity of the zymogen is controlled by the N-terminal activation peptide. The activation peptide is located on top of the active site cleft and sterically prevents access of substrate molecules to the catalytic site. As far as pro-CPB is concerned, this shielding is complete and intrinsic enzymatic activity of the zymogen is.
Cysteine cathepsin C (CatC) is a ubiquitously expressed, lysosomal aminopeptidase involved in the activation of zymogens of immune-cell-associated serine proteinases (elastase, cathepsin G, proteinase 3, neutrophil serine proteinase 4, lymphocyte granzymes, and mast cell chymases). CatC is first synthetized as an inactive zymogen containing an intramolecular chain propeptide, the dimeric form.
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): During the thirties, Northrop, Kunitz and their co-workers gave to the world a set of crystallized enzymes and zymogens.1. They also conveyed a set of corresponding ideas: that certain proteolytic enzymes are produced by the body in precursor form, that these precursors can be activated by slight proteolysis, and that.
