Both chloroplastic and cytosolic phosphoglycerate kinase isozymes are present in the pea leaf nucleus

Phosphoglycerate kinase (EC 2.7.2.3) occurs in chloroplasts, cytosol, and nuclei in higher plants. Immunocytolocalization experiments with isozyme-specific antibodies indicate that both the chloroplastic and the cytosolic forms of the enzyme are present in the pea (Pisum sativum L.) leaf nucleus.
