Most chloroplastic proteins are cytosolically synthesized and posttranslationally transported to their proper locations. Two examples of this group of proteins are ferredoxin and plastocyanin, both of which are metal-containing components of the photosynthetic electron-transport chain. The import process for these two proteins includes the insertion of the metal ions to produce the holo forms of the proteins. We show here that in vitro translated precursor proteins of ferredoxin and plastocyanin are synthesized as apo forms and are assembled into their respective holo forms after being imported into isolated chloroplasts. We also provide evidence that only mature-sized proteins are competent to be assembled into holo forms.
