芳酮 的英文怎麼說
中文拼音 [fāngtóng]
芳酮
英文
arone-
The enzyme 5 - enolpyuvyl - 3 - phosphoshikimic acid synthase ( epsp synthase ; ec2. 5. 1. 19 ), encoded by anoa locus, is a key enzyme present in microorganisms and plants where it has a function in the biosynthesis of aromatic amino acids. glyphosate ( n - phosphonomethyl - glycine ) is an effective non - selective, broad spectrum, postemergence herbicide, which has been shown to inhibit epsp synthase activity in a competitive manner. glyphosate tolerant plants can be mediated by either overproduction of the target enzyme or by the presence of an altered enzyme
