Structural characterization of encapsulated ferritin provides insight into iron storage in bacterial nanocompartments

eLife, 2016
Ferritins are ubiquitous proteins that oxidise and store iron within a protein shell to protect cells from oxidative damage. We have characterized the structure and function of a new member of the ferritin superfamily that is sequestered within an ...

regO: a novel locus in the regulation of tetrapyrrole biosynthesis in Rhodospirillum rubrum

Annals of Microbiology, 2023
Purpose A new locus, regO, involved in the regulation of photosynthesis gene expression in response to oxygen and light, has been studied in Rhodosprillum rubrum ATCC1117 (Rsp. rubrum) for identification of its function.

THE FINE STRUCTURE OF RHODOSPIRILLUM RUBRUM [PDF]

The Journal of Cell Biology, 1963
The fine structure of Rhodospirillum rubrum grown under a series of defined conditions has been examined in thin sections prepared by the methods of Ryter and Kellenberger. In cells grown anaerobically at different light intensities, the abundance of 500 A membrane-bounded vesicles in the cytoplasm is inversely related to light intensity, and directly ...
