Chloroplasts contain a dedicated genome that encodes subunits of the photosynthesis machinery. Transcription genes is predominantly carried out by plastid-encoded RNA polymerase (PEP), nearly 1 MDa complex composed core with homology to eubacterial polymerases (RNAPs) and at least 12 additional chloroplast-specific PEP-associated proteins (PAPs). However, architecture this functions PAPs remain unknown. Here, we report cryo-EM structure 19-subunit PEP from Sinapis alba (white mustard). The...
Magnetotactic bacteria like Magnetospirillum gryphiswaldense are able to orient along magnetic field lines due the intracellular formation of magnetite nanoparticles. Biomineralization has been suggested require a yet-unknown ferritin-like ferrihydrite component. Here, we report identification bacterioferritin as source in M. and show that, contrary previous reports, is not involved biomineralization but required for oxidative stress resistance. Additionally, that an unusual member subfamily...
Organelle-specific protein translocation systems are essential for organelle biogenesis and maintenance in eukaryotes but thought to be absent from prokaryotic organelles. Here, we demonstrate that MamF-like proteins crucial the formation functionality of bacterial magnetosome Deletion mamF-like genes Alphaproteobacterium Magnetospirillum gryphiswaldense results severe defects positioning, biomineralization, magnetic navigation. These phenotypic result disrupted targeting a subset...
Abstract Organelle-specific protein translocation systems are essential for organelle biogenesis and maintenance in eukaryotes but thought to be absent from prokaryotic organelles. Here, we identified that MamF-like proteins involved the formation of bacterial magnetosome organelles share an ancient origin with Tic20 translocases found chloroplasts. Deletion mamF -like genes alphaproteobacterium Magnetospirillum gryphiswaldense results severe defects positioning, biomineralization, magnetic...
