The amoeba Paulinella targets hundreds of proteins into a novel type of photosynthetic organelle. Long imported proteins carry a novel type of N-terminal transit peptide, comprehensive proteome and bioinformatics analyses define the metabolic capacity of this unique organelle. Ancestral host proteins dominate the bacterial to organellar proteome transformation.
