  • Title: Carboxylation and dephosphorylation of phosphoenol-3-fluoropyruvate by maize leaf phosphoenolpyruvate carboxylase.
    Author: Gonzalez DH, Andreo CS.
    Journal: Biochem J; 1988 Jul 01; 253(1):217-22. PubMed ID: 3421944.
    Abstract:
    The analogue (Z)-phosphoenol-3-fluoropyruvate [(Z)-3-fluoro-2-(phosphono-oxy)propenoic acid] was tested as substrate of maize leaf phosphoenolpyruvate carboxylase. Studies with NaH14CO3 indicate that the analogue is carboxylated by the enzyme. However, this reaction accounts for only one-tenth of the activity measured by Pi liberation. The rest of the analogue is merely dephosphorylated. This is the first analogue for which both carboxylation and dephosphorylation have been observed.
