Identification and localization of peroxisomal biogenesis proteins indicates the presence of peroxisomes in the cryptophyte Guillardia theta and other ‘chromalveolates’

Peroxisomes are single-membrane-bound organelles with a huge metabolic versatility, including the degradation of fatty acids (β-oxidation) and the detoxification of reactive oxygen species as most conserved functions. Although peroxisomes seem to be present in the majority of investigated eukaryotes, where they are responsible for many eclectic and important spatially separated metabolic reactions, knowledge about their existence in the plethora...
