Chorismate acid is branch point in aromatic amino acids biosynthesis , related to phenylalanine , bifunctional enzymes chorismate mutase / prephenate dehydratase ( encoded by phea ) is rate - limiting enzyme 分支酸是芳香族氨基酸合成途径的分支点，与苯丙氨酸合成有关，双功能酶分支酸变位酶-预苯酸脱水酶( phea基因编码)是关键酶。

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 ) 目前国内外尚未见有关仅产阿维菌素b1菌株的报道。根据阿维菌素pks基因结构与其聚酮合成反应步骤之间的线性关系，推测b2组分的产生可能是由于阿维菌素pks模块2中脱水酶( dh )的不完全活性所造成。
