Photosynthetic regulatory protein found in animal and bacterial cells

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. Access through your institution Buy or subscribe This is a preview of subscription content, access via your
