我们最近报道了两种蛋白质，同化调节蛋白a（ARPa）和同化调节蛋白B（ARPb），需要光诱导激活某些光合CO2同化酶1，2。ARPa和ARPblink铁氧还蛋白的强还原能力，光化学还原，通过一种机制控制关键酶，到目前为止，被认为是叶绿体特有的3，4。在搜索，以确定这种类型的控制机制的分布，我们已经观察到，更彻底的特点，这些蛋白质，ARPb，广泛存在于活细胞。这些结果提供了证据，铁氧还蛋白连接型叶绿体描述的蛋白质修饰反应发生在非光合以及光合生物。
WE recently reported that two proteins, assimilation regulatory protein a (ARPa) and assimilation regulatory protein b (ARPb), are needed for the light-induced activation of certain enzymes of photosynthetic CO2assimilation1,2. ARPaand ARPblink the strong reducing power of ferredoxin, reduced photochemically, to the control of key enzymes through a mechanism that, until now, was considered to be unique to chloroplasts3,4. In a search to determine the distribution of this type of control mechanism, we have observed that the more thoroughly characterised of these proteins, ARPb, occurs widely in living cells. The results provide evidence that protein modification reactions of the ferredoxin-linked type described for chloroplasts occur in non-photosynthetic as well as photosynthetic organisms.
