chemical modification

基本解释

In further experiments, they found that removal of these proteins depends on the chemical modification of the GluA1 protein.
在進一步的實騐中，他們發現移除這些蛋白質要依賴於GluA1蛋白質的化學改質（chemical modification）。
Other work has focused on histone acetylation, a chemical modification that unwinds DNA from protein spools called histones, thereby enabling gene activity.
其他的工作集中在組蛋白乙醯化，這種化學脩飾可以使DNA從組蛋白纏繞中解離出來，産生基因活性。
Mice lacking this chemical modification of GluA1 recovered fear memories induced by loud tones, whereas littermates that still had normal GluA1 protein did not recover the same fear memories.
缺乏這種GluA1化學改質的老鼠會重新出現由響亮的聲音造成的恐懼記憶，而同窩出生的老鼠中仍然擁有正常GluA1蛋白質的老鼠不會重新出現相同的恐懼記憶。

They made every minor modification they could to that chemical, and came up with the MLN4670 molecule.
