Putrescine may be a natural stimulator of glucose-6-phosphate dehydrogenase.
The possible relationship between pyridoxal phosphate-dependent ornithine decarboxylase (ODC) activity and glucose-6-phosphate dehydrogenase (G6PD) activity has been studied in the osteoblasts of the growth-plate of metatarsals of rats fed a pyridoxine-deficient diet, which caused depressed G6PD levels. The G6PD activity was fully restored when it was assayed in the presence of putrescine. It is suggested that this relationship may account for the correlation generally found between growth and ODC activity.
