Enzyme Substrates
Enzyme substrates are molecules upon which enzymes act to catalyze chemical reactions. The substrate binds to the active site of the enzyme, where it undergoes a specific transformation to form the product of the reaction. Enzyme substrates are essential tools in research for studying enzyme kinetics, specificity, and mechanism of action. They are also used in diagnostic assays and biochemical studies. At CymitQuimica, we provide a diverse selection of high-quality enzyme substrates to support your research in enzymology and biochemistry.

CAS:The maunfacturing of blue jeans started 150 years ago as workwear, and are found nowadays in almost every wardrobe. Their renowned indigo color tone is truly unique; nevertheless, the high demand for the dye poses serious sustainability and environmental problems connected with its manufacturing process. Recently, a group of scientists presented an alternative indigo dyeing method inspired by the indoxyl glucoconjugate present in the plant P.tinctorium. The researchers proposed as an alternative approach a biocatalytic process using recombinant E.coli to access water soluble β-gluco-indoxyl (indican). At the point of coloring, indican gets hydrolyzed by β-glucosidase enzymes forming indoxyl, which suddenly undergoes oxidation to leucoindigo and further crystallizes to indigo giving the typical blue denim its signature character.Formula:C14H17NO6Purity:Min. 99.0 Area-%Molecular weight:295.29 g/molTyramine
