Phosphorylation of IcsA by cAMP-dependent protein kinase and its effect on intracellular spread of Shigella flexneri.

Molecular microbiology - 1 Apr 1992

d'Hauteville H, Sansonetti P J

Abstract excerpt

Shigella flexneri, a Gram-negative bacillus belonging to the family Enterobacteriaceae, causes bacillary dysentery in humans by invading colonic epithelial cells. Processes by which epithelial cells, which are not professional phagocytes, may limit the spread of the invading microorganisms are poorly understood. This paper shows that IcsA (VirG), a 120 kDa bacterial outer membrane protein responsible for...
