CheKine™ Micro ACL Activity Assay Kit: Your Top Questions Answered
H3: What is ATP citrate lyase (ACL) and why does it matter? ATP citrate lyase (ACL, EC 2.3.3.8) is the enzyme that catalyzes the conversion of citrate and CoA to acetyl-CoA and oxaloacetate, using ATP as an energy source. This reaction links carbohydrate metabolism to lipid synthesis—it's the bridge between the TCA cycle and de novo lipogenesis. ACL is highly expressed in lipogenic tissues like liver and adipose tissue, and its activity is upregulated in many cancers to support lipid biosynthesis for membrane production and signaling. H3: Why is ACL a hot topic in cancer research? ACL is the primary source of acetyl-CoA for fatty acid synthesis in cancer cells. Tumor cells rely on de novo lipogenesis for membrane biogenesis, protein…
