| 摘要 |
<p>The present invention relates to a ginseng-derived cytochrome P450 enzyme CYP716A53v2 gene which is involved in protopanaxatriol biosynthesis, and more specifically relates to, inter alia: a protopanaxatriol biosynthesis promoting composition comprising ginseng-derived CYP716A53v2 protein or a CYP716A53v2 gene coding therefor; a recombinant vector or plasmid comprising the CYP716A53v2 gene; and a method for increasing protopanaxatriol production by increasing expression of the CYP716A53v2 gene or the direct production of protopanaxatriol from a transformant resulting from genetic alteration by means of the composition. The ginseng-derived CYP716A53v2 gene according to the present invention, which is involved in protopanaxatriol biosynthesis, can be used advantageously in a method for synthesising protopanaxatriol in volume or increasing the biosynthesis of protopanaxatriol-based ginseng saponins.</p> |
