Osmoregulated periplasmic glucans (OPGs) are a family of periplasmic oligosaccharides found in the envelope of most Proteobacteria. They are required for virulence of zoo- and phyto-pathogens. The glucose backbone of OPGs is substituted by various kinds of molecules depending on the species, O-succi

NFAT5 is an osmoregulated transcription factor that particularly increases expression of genes involved in protection against hypertonicity. Transcription factors often contain unstructured regions that bind co-regulatory proteins that are crucial for their function. The n-terminal region of NFAT5 c

New insights into the biological role of the osmoregulated periplasmic glucans in pathogenic and symbiotic bacteria.

Bontemps-Gallo S1, Lacroix JM2.
Environmental microbiology reports.Environ Microbiol Rep.2015 Oct;7(5):690-7. doi: 10.1111/1758-2229.12325. Epub 2015 Sep 10.
This review emphasizes the biological roles of the osmoregulated periplasmic glucans (OPGs). Osmoregulated periplasmic glucans occur in almost all α-, β- and γ-Proteobacteria. This polymer of glucose is required for full virulence. The roles of the OPGs are complex and vary depending on the speci
