WebA procedure is described for the purification of phosphopyruvate (PEP) carboxylase (EC 4.1.1.31) from extracts of Escherichia coli, strain W. The enzyme, purified 160-fold, catalysed the stoicheiometric formation of oxaloacetate from phosphopyruvate and potassium bicar? bonate. This reaction occurred most readily at pH 8-5, and required the ... WebTryptophan, administered to rats, inhibits gluconeogenesis, but increases the activity of hepatic phosphopyruvate carboxylase when assayed in vitro. Quinolinate, a metabolite of tryptophan, inhibits gluconeogenesis in perfused livers, and inhibits phosphopyruvate carboxylase in liver cytosol from tryptophan-treated rats but not from normal rats.
