Substratos enzimáticos
Substratos enzimáticos são moléculas sobre as quais as enzimas atuam para catalisar reações químicas. O substrato liga-se ao sítio ativo da enzima, onde passa por uma transformação específica para formar o produto da reação. Os substratos enzimáticos são ferramentas essenciais na pesquisa para estudar a cinética enzimática, especificidade e mecanismo de ação. Eles também são usados em ensaios diagnósticos e estudos bioquímicos. Na CymitQuimica, oferecemos uma seleção diversificada de substratos enzimáticos de alta qualidade para apoiar suas pesquisas em enzimologia e bioquímica.

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.
