Abstract
|
|
|
|
Palmitoyl CoA was found to inhibit corn embryo axis glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase, which were also inhibited 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 polyamines, respectively. Such results suggest that fatty acid biosynthesis and lypolysis could be regulated to some extent by polyamines in corn embryo axis.
