Phosphopyruvate carboxylase

WebIt has been shown that the enzyme phosphoenol pyruvate carboxylase (EC 4.1.1.31) is present in the pericarp and is 100 times as active in carbon dioxide fixation as ribulose diphosphate carboxylase (EC 4.1.1.39). Other enzymes present in the pericarp are phosphoenol pyruvate synthetase, pyrophosphatase (EC 3.6.1.1), malate NAD and NADP ...

WebAnalysis of extracts of the mutant, and of its parent organism, showed that the former lacked phosphopyruvate carboxylase activity (EC 4.1.1.31), although other enzymes capable in theory of catalysing the carboxylation of C 3 -acids were abundant in both extracts. 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 ...
