Studies on Enzyme Activities Responsible for Biosynthesis of Putrescine in Ginseng(Panax ginseng C.A. Meyer)

인삼에서 Putrescine 합성에 관련된 효소활성에 관한 연구

Specific activities of ADC and ODC from 2-4 year old ones were higher than that from seedlings whereas those activities were not changed significantly from 2 to 4 years. Generally, activity of ADC was predorminant compared to that of ODC. Free arginine content in roots was much higher than that of leaves. And arginase specific activity from roots was higher than that of leaves. Cumulative results suggest that putrscine formation from ornithine in roots may be more effective than leaves and contribute to putrescine biosynthesis to some extract.
