Spatial proteomics reveals carboxysome adaptation and mitochondrial proteome in Paulinella chromatophora.
The Rhizarian amoeba Paulinella chromatophora represents a unique case of primary endosymbiosis, which has acquired photosynthetic organelles (chromatophores) independently of the endosymbiosis event that gave rise to plastids. Using localization of organelle proteins by isotope tagging following differential centrifug...
