Abstract
(EN) Provided are a taxadiene synthase TcTS2, a encoding nucleotide sequence and use thereof. The amino acid sequence of TcTS2 comprises or consists of (a) an amino acid sequence set forth in SEQ ID NO: 1; or (b) a functional homologous sequence having at least 80% sequence similarity with the amino acid sequence set forth in SEQ ID NO: 1; or (c) an amino acid sequence having TcTS2 activity with addition, deletion, or substitution of one or more amino acids to the amino acid sequence set forth in SEQ ID NO: 1. The TcTS2 and the nucleotide sequence encoding the TcTS2 provide new gene resources for improving the yield of paclitaxel, can be used for modifying chassis hosts by means of plant genetic engineering and metabolic engineering strategies and producing paclitaxel and intermediates and the like thereof, and have significant economic and social value.
(FR) L'invention concerne une taxadiène synthase TcTS2, une séquence nucléotidique codante et son utilisation. La séquence d'acides aminés de TcTS2 comprend ou consiste en (a) une séquence d'acides aminés représentée dans SEQ ID NO : 1 ; ou (b) une séquence homologue fonctionnelle ayant au moins 80 % de similarité de séquence avec la séquence d'acides aminés représentée dans SEQ ID NO : 1 ; ou (c) une séquence d'acides aminés ayant une activité TcTS2 avec addition, délétion ou substitution d'un ou plusieurs acides aminés à la séquence d'acides aminés représentée dans SEQ ID NO : 1. Le TcTS2 et la séquence nucléotidique codant pour le TcTS2 fournissent de nouvelles ressources génétiques pour améliorer le rendement en paclitaxel, peuvent être utilisés pour modifier des hôtes châssis au moyen de stratégies de génie génétique végétal et de génie métabolique et produire du paclitaxel et des intermédiaires et similaires, et ont une valeur économique et sociale significative.
(ZH) 提供了一种紫杉二烯合酶TcTS2，编码核苷酸序列及其应用。TcTS2的氨基酸序列包含或由如下序列组成：a)SEQ ID NO.1所示的氨基酸序列；或，b)与SEQ ID NO.1所示的氨基酸序列具有至少80％序列相似性的功能性同源序列；或c)在SEQ ID NO.1所示的氨基酸序列中添加、缺失、替换一个或多个氨基酸且具有TcTS2活性的氨基酸序列。TcTS2和编码TcTS2的核苷酸序列，为提高紫杉醇的产量提供了新的基因资源，可用于植物基因工程和代谢工程策略改造底盘宿主，生产紫杉醇及其中间体等，具有显著经济和社会价值。
