RESUMO
An enriched IgG serum fraction obtained from rabbits immunized against pea chloroplast fructose-1,6-bisphosphatase (FBPase) was used, coupled to colloidal gold (15 nanometer particles) goat anti-rabbit IgG, to analyze by electron microscopy the location of photosynthetic FBPase in pea (Pisum sativum L.) leaf ultrathin sections. In accordance with earlier biochemical studies on distribution of FBPase activity, the enzyme was visualized both in the stromal space and bound to the chloroplast membranes. Some gold particles also appear in the cytoplasm, which can be related to the presence in the cytosol of a high molecular weight precursor of this nuclear coded enzyme.
