Opis: Collagenases degrade native helical collagen fibrils. The enzyme has an important role in connective tissue metabolism and is produced by specific cells involved in repairs and remodelling processes. It is a type II enzyme that contains greater clostripain activity. It is generally used for heart, bone, muscle, thyroid, cartilage, and liver cells. Ca²⁺ is required for its activation while metal chelating agents such as cysteine, EDTA or o-phenanthroline inhibits its activity.

Opis: Activators: Ca²⁺ is required. Inhibitors: Metal chelating agents such as cysteine, EDTA or o-phenanthroline but not DFP. It is also inhibited by a2-macroglobulin - a large plasma glycoprotein. The human skin enzyme is inhibited by human serum but granulocyte collagenase is not. Human serum contains a2-macroglobulin and a1-antitrypsin that may inhibit certain collagenases.

Opis: Xaa-Pro aminopeptidase 2 (XPNPEP2) belongs to the peptidase M24B family of metalloproteases. Human XPNPEP2 is widely expressed in various tissues, such as kidney, lung, heart, placenta, liver, small intestine and colon. However, it doesn’t express in brain, skeletal muscle, pancreas, spleen, thymus, prostate, testis and ovary. XPNPEP2 is a Homotrimer which binds 2 manganese ions per subunit. The metalloprotease XPNPEP2 may play a role in the inflammatory process and other reactions produced in response to injury or infection and the metabolism of the vasodilator bradykinin.

Opis: Cystathionine Gamma-Lyase (CTH) belongs to the trans-sulfuration enzymes family. CTH exists as a homotetramer and interacts with CALM in a calcium-dependent manner. CTH breaks down cystathionine into cysteine, ammonia and 2-oxobutanoate. CTH catalyses the last step in the trans-sulfuration pathway from methionine to cysteine and has broad substrate specificity. Defects in CTH will lead to cystathioninuria, which is an autosomal recessive phenotype characterised by abnormal accumulation of plasma cystathionine.

Opis: Tryptophan synthase is a multienzyme alpha2 beta 2 complex composed of two protein subunit. Tryptophan synthase catalyses the last two steps in the synthesis of L-tryptophan (L-Trp). The alpha-subunit catalyses cleavage of 3-indole-d-glycerol 3′-phosphate (IGP) to give indole and D-glyceraldehyde 3′-phosphate (G3P). Indole is then transferred through a 25-Å hydrophobic tunnel to the beta -subunit. The beta 2 subunit contains pyridoxal 5'-phosphate and catalyses several pyridoxal 5'-phosphate-dependent reactions, including/3-elimination reactions 6 and a thiol-dependent transamination reaction. This enzyme is commonly found in Eubacteria, Archaebacteria, Protista, Fungi, and Plantae, but is absent from Animalia. As humans do not have tryptophan synthase, this enzyme has been explored as a potential drug target.

Opis: beta Galactosidase is a lysosomal beta Galactosidase that hydrolyses the terminal beta Galactose from Ganglioside and Keratan sulfate. In lysosome, the mature beta Galactosidase protein associates with Cathepsin A and Neuraminidase 1 to form the lysosomal multienzyme complex . An alternative splicing at the RNA level of beta Galactosidase results a catalytically inactive beta Galactosidase that plays an important role in vascular development. Defects of beta -galactosidase (GLB1) are the cause of diseases like GM1-gangliosidosis which is a lysosomal storage disease and Morquio Syndrome B that cause patients to have abnormal elastic fibers. More than 100 mutations have been identified for beta Galactosidase, which result in different residual activities of the mutant enzymes and a spectrum of symptoms in the two related diseases.

Opis: Uridinephosphorylase 1 (UPP1) is a member of the family of pentosyltransferase. UPP1 catalyses the reversible phosphorolysis of uridine to uracil. The expression levels and the enzymatic activity of UPP1 are higher in human solid tumors than in adjacent normal tissues. The high level of UPP1 expression in some tumors makes it a potential prognosticfactor for some cancers, such as oral squamous cell carcinoma. UPP1 is important for the homeostatic regulation of intracellular and plasma uridine concentratios. UPP1 plays an important role in the pyrimidine salvage pathway through its catalysis of the reversible phosphorolysis of uridine to uracil.

Opis: Exonuclease I acts specifically on single-stranded DNA degrading it processively in the 3'- to 5'-direction, producing 5'-mononucleotides. Applications include eliminating residual single-stranded DNA containing a 3'-terminus, measuring endonucleolytic cleavage of covalently closed circular (ccc) ssDNA, measuring DNA helicase activity.

Opis: This purified calf intestinal alkaline phosphatase (CIP) is supplied in Tris buffer and 50% glycerol for use in protein research methods. The main applications for alkaline phosphatase in molecular biology and protein research are to remove 5'-phosphate groups from DNA or as a reporter system for immunoassays such as ELISA. For these latter methods, the enzyme is usually conjugated to specific primary or secondary antibodies and its activity is detected with a color-forming (or light-generating) substrate.
