Phosphoenolpyruvate (2-phosphoenolpyruvate, PEP) is the carboxylic acid derived from the enol of pyruvate and phosphate. It exists as an anion. PEP is an important intermediate in biochemistry. It has the highest-energy phosphate bond found (−61.9 kJ/mol) in organisms, and is involved in glycolysis and gluconeogenesis.
Post-exposure prophylaxis, also known as post-exposure prevention (PEP), is any preventive medical treatment started after exposure to a pathogen in order to prevent the infection from occurring. It should be contrasted with pre-exposure prophylaxis , which is used before the patient has been exposed to the infective agent.
Phosphoenolpyruvate carboxylase (also known as PEP carboxylase, PEPCase, or PEPC; EC 4.1.1.31, PDB ID: 3ZGE) is an enzyme in the family of carboxy-lyases found in plants and some bacteria that catalyzes the addition of bicarbonate (HCO 3 −) to phosphoenolpyruvate (PEP) to form the four-carbon compound oxaloacetate and inorganic phosphate: [1]
PEP (phosphoenol pyruvate) group translocation, also known as the phosphotransferase system or PTS, is a distinct method used by bacteria for sugar uptake where the source of energy is from phosphoenolpyruvate (PEP). It is known to be a multicomponent system that always involves enzymes of the plasma membrane and those in the cytoplasm.
X-ray structures of PEPCK provide insight into the structure and the mechanism of PEPCK enzymatic activity. The mitochondrial isoform of chicken liver PEPCK complexed with Mn 2+, Mn2+-phosphoenolpyruvate (PEP), and Mn 2+-GDP provides information about its structure and how this enzyme catalyzes reactions. [10]
PEP status also extends to relatives and close associates. Relatives and close associates include a spouse, a partner, children and their spouses or partners and parents. While other family members may not qualify under this definition, it may be appropriate to consider that other family members can also be used as a front for corrupt activities.
Pep was a brand of whole-wheat breakfast cereal produced by the Kellogg Company, and introduced in 1923, which became the first to be fortified with vitamins B and D in 1938. [1] Pep was a long-running rival to Wheaties , and also the sponsor of Mutual Radio 's The Adventures of Superman radio series. [ 2 ]
