Cell Biological Studies on the Mechanism of Development and Differentiation Ⅷ 3. Effects of Polyamines on the Activities of Corn Glucose-6-Phosphate Dehydrogenase, 6-Phosphogluconate Dehydrogenase, and Protein Kinase

생체발생 및 분화기구의 세포생물학적 연구 Ⅷ 3. Polyamine이 옥수수 배의 Glucose-6-Phosphate Dehydrogenase, 6-Phosphogluconate Dehydrogenase 및 Protein Kinase 활성에 미치는 영향

Palmitoyl CoA was found to inhibit corn embryo axis glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase, which were also inhibites by polyamines. However, reversal of inhibition of both enzymes by palmitoyl CoA was made by spermine. Activity of corn embryo axis protein kinase was found to increase steadily after germination. Activation and inhibition of protein kinase were made by MgCl$_2$and all polymines, respectively. Suc results suggest that fatty acid biosynthesis and lypolysis could be regulated to some extent by polyamines in corn embryo axis.
