Abstract
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 CO2 assimilation1,2. ARPa and ARPb link 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.
