Substrats d'enzymes
Les substrats enzymatiques sont des molécules sur lesquelles les enzymes agissent pour catalyser des réactions chimiques. Le substrat se lie au site actif de l'enzyme, où il subit une transformation spécifique pour former le produit de la réaction. Les substrats enzymatiques sont des outils essentiels dans la recherche pour étudier la cinétique enzymatique, la spécificité et le mécanisme d'action. Ils sont également utilisés dans les essais diagnostiques et les études biochimiques. Chez CymitQuimica, nous offrons une sélection diversifiée de substrats enzymatiques de haute qualité pour soutenir vos recherches en enzymologie et biochimie.

Caspases are a family of protease enzymes playing essential roles in programmed cell death and inflammation. The acronym caspase stands for Cysteine Aspartic Acid Specific Protease due to their specific cleavage of an aspartic acid residue, by mean of a cysteine in the catalytic site of the enzyme._x000D_About 11 or 12 different caspases are known in humans and 10 in mice, participating in numerous different cellular functions. Caspase deficiency, for example, has been identified as a cause of tumor development, while over-activation of some caspases such as caspase-3 can lead to excessive apoptosis that can be observed in several neurodegenerative diseases. Caspases cleave proteins at specific peptide recognition sequences. Ac-DEVD-6-Amino-D-Luciferin (Ac-Asp-Glu-Val-Asp-6-Amino-D-Luciferin, Cat.No_x000D_L-8282) is a synthetic chemiluminescent peptide for the determination of caspase-3 and caspase-7activity.
