A photosystem I (PSI)-fucoxanthin chlorophyll protein (FCP) complex with a chlorophyll a/P700 ratio of approximately 200:1 was isolated from the diatom Phaeodactylum tricornutum. Spectroscopic analysis proved that the more tightly bound FCP functions as a light-harvesting complex, actively transferring light energy from its accessory pigments chlorophyll c(More)
Thylakoids of the diatom Cyclotella meneghiniana were separated by discontinuous gradient centrifugation into photosystem (PS) I, PSII, and fucoxanthin-chlorophyll protein (FCP) fractions. FCPs are homologue to light harvesting complexes of higher plants with similar function in e.g. brown algae and diatoms. Still, it is unclear if FCP complexes are(More)
Eukaryotic ribosome biogenesis requires the concerted action of numerous ribosome assembly factors, for most of which structural and functional information is currently lacking. Nob1, which can be identified in eukaryotes and archaea, is required for the final maturation of the small subunit ribosomal RNA in yeast by catalyzing cleavage at site D after(More)
Eukaryotic ribosome biogenesis requires the concerted action of ~200 auxiliary protein factors on the nascent ribosome. For many of these factors structural and functional information is still lacking. The endonuclease Nob1 has been recently identified in yeast as the enzyme responsible for the final cytoplasmatic trimming step of the pre-18S rRNA during(More)
