研究人员发现，蛋壳只有在一种蛋白质的催化下才能形成，而这种物质只存在于鸡的卵巢内。

Researchers found that the formation of egg shells relies on a protein found only in a chicken’s ovaries, according to The Sun of London.

他们也可以像蛋白质一样催化反应。

And they can catalyse reactions, as proteins do, too.

One way that you could switch this on and off inside the cell is by taking off this phosphorous, proteins enzymes that do this opposite reaction, the opposite to kinases are called phosphokinases.

一种方法是通过去除磷酸基团,来改变细胞内蛋白的状态,催化添加磷酸基团,此逆反应的蛋白酶,能够催化逆反应的激酶叫做磷酸激酶

If that protein is an enzyme then you've and you've switched it from an 'off' position where it's not catalyzing a reaction to an 'on' position where it is, you've changed the biochemical state of the cell, you've changed the chemical reactions that can occur within the cell, and you've changed its behavior.

如果这种蛋白是一种酶的话,你就能够将酶从无催化作用的静息态,激活至能催化反应的激活态,你改变了细胞的生化状态,也改变了细胞内发生的化学反应,改变了细胞的行为

It performs a chemical reaction on the protein, taking a phosphorous from ATP and moving that phosphorous onto the protein.

它能够催化蛋白参与如下反应,即将ATP上的一个磷酸基团,转移到蛋白质上
