摘要:草甘膦[ N-(膦酰基甲基)甘氨酸]是一种广谱的芽后除草剂,是全球使用最广泛的农用化学品之一.在过去的30年中,抗草甘膦的杂草得到了发展,这对种植者和农作物科学家构成了巨大的挑战,导致农作物产量降低和成本增加.3,6-二氯-2-甲氧基苯甲酸(麦草畏)是xtendimax®的活性成分,Xtendimax®是拜耳作物科学公司开发的用于控制阔叶杂草(包括抗草甘膦的物种)的独立除草剂.3,6-二氯-2-羟基苯甲酸(3,6-Dcsa)是麦草畏合成中的倒数第二个中间体.现有的麦草畏制造路线利用高温高压kolbe-Schmitt羧化反应制备3,6-Dcsa.这封信中描述的是一种新的非柯尔布-施密特流程,该流程准备3,

权利人:KUMIAI CHEMICAL INDUSTRY CO
摘要:An object of the present invention is to identify an enzyme having activity of synthesizing dihydrotentoxin that is a tentoxin precursor and an enzyme having activity of synthesizing tentoxin using dihydrotentoxin as a substrate. The present invention concerns a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 16 and having activity of nonribosomal peptide synthesis of dihydrotentoxin and a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 18 and having activity of converting dihydrotentoxin to tentoxin.
