In the assay, PEP is converted to ATP and pyruvate. The generated pyruvate is quantified by colorimetric (λmax = 570 nm) or fluorometric methods (Ex\/Em = 535\/587 nm). The assay is simple, sensitive and reliable. The detection limit is approximately 1 µM PEP in biological samples.\u003cbr\u003e\nThis product is manufactured by BioVision, an Abcam company and was previously called K365 PEP Colorimetric\/Fluorometric Assay Kit. K365-100 is the same size as the 100 test size of ab204713.\u003cbr\u003e\nThe Safety Datasheet for this product has been updated for certain countries.

Alternate names include phosphoenolpyruvic acid. It is a phosphorylated compound with a molar mass of 167.07 g\/mol. In cells PEP is generated via the enolase enzyme converting 2-phosphoglycerate to PEP. Its high-energy phosphate group makes it critical for ATP generation in glycolysis. This molecule is expressed in the cytoplasm of all living organisms reflecting a fundamental role in cellular metabolism.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThe role of phosphoenolpyruvate extends beyond glycolysis. It acts as a significant player in gluconeogenesis aiding in the conversion of lactate and other substrates into glucose. PEP is an important precursor for several biosynthetic pathways including amino acid synthesis. It is not part of a molecular complex but interacts with several enzymes such as pyruvate kinase that facilitate its conversion into pyruvate releasing energy stored in its phosphate bond.\u003cbr\u003e\nPathways\u003cbr\u003e\nPhosphoenolpyruvate is central to both glycolysis and gluconeogenesis. It stands at a critical juncture in the glycolytic pathway where the PEP to pyruvate conversion catalyzed by pyruvate kinase is a major step for ATP synthesis. In gluconeogenesis PEP converts back to glucose ensuring energy balance during fasting states. PEP is closely related to proteins such as pyruvate kinase and enolase which are key players in the glycolytic and gluconeogenic pathways respectively.\u003cbr\u003e\nAlterations in phosphoenolpyruvate metabolism connect to various health conditions including cancer and diabetes. For instance dysregulated glycolysis involving PEP often occurs in cancer cells exhibiting the Warburg effect characterized by high rates of glycolysis even under oxygenated conditions. Diabetes also shows links to abnormal PEP levels affecting glucose production and metabolism. Pyruvate kinase related to PEP is another protein implicated in these disorders highlighting its role in metabolic and energy homeostasis.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46855620264105,"sku":"ab204713","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab204713","provider":"Iright","version":"1.0","type":"link"}
