- W2009675204 abstract "Illumination of previously darkened maize (Zea mays L. cv Golden Cross Bantam T51) leaves had no effect on the concentration of phosphoenolpyruvate (PEP) carboxylase protein, but increased enzyme activity about 2-fold when assayed under suboptimal conditions (pH 7.0 and limiting PEP). In addition, sensitivity to effectors of PEP carboxylase activity was significantly altered; e.g. malate inhibition was reduced and glucose-6-phosphate activation was increased. Consequently, 10- to 20-fold differences in PEP carboxylase activity were observed during dark to light transitions when assayed in the presence of effectors. At pH 7.0 activity of purified PEP carboxylase was not proportional to enzyme concentrations. Below 0.7 microgram PEP carboxylase protein per milliliter, enzyme activity was disproportionately reduced. Including polyethylene glycol plus potassium chloride in the reaction mixture eliminated this discontinuity and substantially increased PEP carboxylase activity and reduced malate inhibition dramatically. Inclusion of polyethylene glycol in the assay mixture specifically increased the activity of PEP carboxylase extracted from dark leaves, and reduced malate inhibition of the enzyme from both light and dark leaves. Collectively, the results suggest that PEP carboxylase in maize leaves is subjected to some type of protein modification that affects both activity and effector sensitivity. We postulate that changes in quaternary structure (dissociation or altered subunit interactions) may be involved." @default.
