Expression of this truncated gene in plant was expected to give information about expression in plant of high g + c content genes but no antifungal activity was expected in this stage
由於載體中2 . 7kb的pks基因編碼了兩種酶活性的結構域而不是完整的型pks模塊,因此我們目前並不期望這個截短的pks基因在植物能產生抗真菌活性。In consideration of the colinearity between the activities of avermectin pks domains and structure of the polyketide product, the dh2 domain of avermectin pks, which corresponds to c - 22, 23 dehydration, appears to have partial dehydratase activity and this results in a mixture of c - 22, 23 double bonds ( " 1 " components ) and c23 hydroxy compounds ( " 2 " components )
目前國內外尚未見有關僅產阿維菌素b1菌株的報道。根據阿維菌素pks基因結構與其聚酮合成反應步驟之間的線性關系,推測b2組分的產生可能是由於阿維菌素pks模塊2中脫水酶( dh )的不完全活性所造成。
