Salt-inducible putative ABC transporter periplasmic binding protein; Hyperosmotically inducible periplasmic protein; Protein involved in response to osmotic stress.

Osmotically-inducible lipoprotein; Activator of ntrL gene; Protein involved in transcription activator activity, transcription and response to osmotic stress.

Uncharacterized protein; Highly specific potassium binding protein that is required for normal growth in the presence of high levels of external K(+). May act as a sensor of cytoplasmic K(+) concentration. Binds a single K(+) ion, which induces a large conformational change. Can also bind the larger alkali metal ions Rb(+) and Cs(+), and NH(4)(+). May be involved in the regulation of peptidoglycan cross-linking.

Osmotically and stress inducible lipoprotein; Provides resistance to osmotic stress. May be important for stationary-phase survival.

Stationary-phase-induced ribosome-associated protein; Although this protein associates with the 30S subunit of the ribosome it is not considered to be a bona fide ribosomal protein. Belongs to the SRA family.

Putative membrane-anchored DUF883 family ribosome-binding protein; Belongs to the ElaB/YgaM/YqjD family.

Fe-binding and storage protein; During stationary phase, binds the chromosome non- specifically, forming a highly ordered and stable dps-DNA co-crystal within which chromosomal DNA is condensed and protected from diverse damages. It protects DNA from oxidative damage by sequestering intracellular Fe(2+) ion and storing it in the form of Fe(3+) oxyhydroxide mineral, which can be released after reduction. One hydrogen peroxide oxidizes two Fe(2+) ions, which prevents hydroxyl radical production by the Fenton reaction. Dps also protects the cell from UV and gamma irradiation, iron and cop [...]

Membrane-anchored ribosome-binding protein; Upon overexpression inhibits growth.

Superoxide dismutase, Cu, Zn, periplasmic; Destroys radicals which are normally produced within the cells and which are toxic to biological systems.
