Albaflavenone和strepsesquitriol生物合成基因簇在链霉菌SR107菌株中的异源表达揭示二者有共同的生物合成前体epi-isozizaene(英文)
Heterologous expression of albaflavenone and strepsesquitriol gene clusters in Streptomyces sp.SR107 unveils both share the same precursor epi-isozizaene
【摘要】 三环倍半萜albaflavenone和strepsesquitriol的结构相似,但是其亚甲基桥的位置不同。在链霉菌Streptomyces sp.SR107菌株中,异源表达两个双基因基因簇scp和wcp,均产生同一个化合物4β,5β-epoxy-2-epi-zizaan-6β-ol(4),表明albaflavenone(2)和strepsesquitriol(3)可能来源于同一前体epi-isozizaene(1)。
【Abstract】 The tricyclic sesquiterpenes albaflavenone(2) and strepsesquitriol(3) share the similar structure except the linkage of their methylene bridges in different position.Heterologous expression both of the two-gene clusters(scp and wcp) in the Streptomyces sp.SR107 strain led to the generation of the same compound 4β,5β-epoxy-2-epi-zizaan-6β-ol(4),indicating that these two sesquiterpenes may share the same precursor epi-isozizaene(1).
