摘 要：The oxidative pentose-phosphate pathway （OPPP） represents a central branch of cellular metabolism emanating from glucose-6-phosphate （G6P） to provide reductive power （NADPH） and sugar phosphates for anabolic biosyntheses. In plant cells, the oxidative OPPP branch is found in the cytosol and in plastids, consisting of glucose-6-phosphate dehydrogenase （G6PD）, 6-phosphogluconolactonase （PGL）, and 6-phosphogluconate dehydrogenase （6PGD）. These enzymes are encoded by small gene families in the nuclear genome, which, in Arabidopsis, comprise six G6PD, five 6-PGL, and three 6-PGD isoforms （Kruger and von Schaewen, 2003）. Specific targeting motifs at the C-terminus of 6-PGL and 6-PGD isoforms suggested that the OPPP may also occur in peroxisomes （Reumann et al., 2004）.
