Abstract:
Glucose-6-phosphate dehydrogenase (G6PDH) catalyzes the first and rate-limiting step of the oxidative pentose phosphate pathway, existing in both cytosolic and plastidic compartments of higher plants. Its main function is to provide reducing power (NADPH) and pentose phosphates for reductive biosynthesis and maintenance of the redox state of the cell. In addition, the expression of this enzyme is related to different biotic and abiotic stresses. In this review, we analyzed the isoenzyme, regulation and biological function of G6PDH. Meanwhile, we summarized the progress work of G6PDH involved in stress resistance, gene cloning, enzyme-deficiency and cluster analysis. Problems should be solved were also discussed.
