Transport of nuclear-encoded proteins into secondarily evolved plastids

Keywords: protein targeting, secondary endosymbiosis, secondary plastids,

Many algal groups evolved by the engulfment and intracellular reduction of a eukaryotic phototroph within a heterotrophic cell. By this process so-called secondary plastids evolved, surrounded by three or four membranes. In these organisms most of the genetic material encoding plastid functions is localised in the cell nucleus, with the result that many proteins have to pass three, four, or even five membranes to reach their final destination within the plastid. In this article, we review recent models and findings, which help to explain important cellular mechanisms involved in the complex protein transport process into secondary plastids.
