Homology Modeling of Phosphoenolpyruvate Carboxykinase of Ascaris suum
Phosphoenolpyruvate carboxykinase (PEPCK) is present in parasites as well as in their mammalian hosts it serves different functions. In the host PEPCK catalyses the reaction from oxaloacetate to make phosphoenol pyruvate and carbon dioxide, part of the gluconeogenesis pathway. Parasite PEPCK catalyses the reverse reaction to form oxaloacetate, the precursor of malate, which is metabolized anaer...
متن کاملPhosphoenolpyruvate carboxykinase as the sole anaplerotic enzyme in Saccharomyces cerevisiae.
Pyruvate carboxylase is the sole anaplerotic enzyme in glucose-grown cultures of wild-type Saccharomyces cerevisiae. Pyruvate carboxylase-negative (Pyc(-)) S. cerevisiae strains cannot grow on glucose unless media are supplemented with C(4) compounds, such as aspartic acid. In several succinate-producing prokaryotes, phosphoenolpyruvate carboxykinase (PEPCK) fulfills this anaplerotic role. Howe...
متن کاملIn silico Homology Modeling and Epitope Prediction of NadA as a Potential Vaccine Candidate in Neisseria meningitidis
Neisseria meningitidis is a facultative pathogen bacterium which is well founded with a number of adhesion molecules to facilitate its colonization in human nasopharynx track. Neisseria meningitidis is a major cause of mortality from sever meningococcal disease and septicemia. The Neisseria meningitidis adhesion, NadA, is a trimeric autotransporter adhesion molecule which is involved in cell ad...
متن کاملMolecular characterization, enzyme properties and transcriptional regulation of phosphoenolpyruvate carboxykinase and pyruvate kinase in a ruminal bacterium, Selenomonas ruminantium.
To elucidate the regulatory mechanism for propionate production in Selenomonas ruminantium, the molecular properties and gene expression of phosphoenolpyruvate carboxykinase (Pck) and pyruvate kinase (Pyk) were investigated. The Pck was deduced to consist of 538 aa with a molecular mass of 59.6 kDa, and appeared to exist as a monomer. The Pyk was revealed to consist of four identical subunits c...
متن کاملPurification of phosphoenolpyruvate carboxykinase from the cytosol fraction of rat liver and the immunochemical demonstration of differences between this enzyme and the mitochondrial phosphoenolpyruvate carboxykinase.
Phosphoenolpyruvate carboxykinase (EC 4.1.1.32) has been isolated and purified from the cytosol fraction of rat liver to give a specific activity of 14 to 16 moles of bicarbonate tied per min per mg of protein. The enzyme is homogeneous on disc electrophoresis and Sephadex G-100 chromatography and has a molecular weight of 74,500 with an isoelectric point of 5.04. Antibodies prepared in rabbits...
