WebOct 5, 2016 · With specific antibody against the enzyme we have shown that the increase in phosphopyruvate carboxylase is partially mediated via an actinomycin D-sensitive increase in enzyme synthesis. 2. In starved animals tryptophan increases the enzyme activity without any change in the relative rate of phosphopyruvate carboxylase synthesis. Webthe anaplerotic function is borne by phosphopyruvate carboxylase (EC 4.1.1.31) and that mutants devoid of this enzymic activity cannot maintain a functioning tricarboxylic acid cycle during the utilization of such substrates, although other enzymes are present which, in theory, could bring about the net formation of C4-acids from C3-precursors.
