| Additional Information | 1) NleB, N-acetylglucosamine (GlcNAc) transferase modify a conserved arginine in death domains proteins of the host such as TRADD and FADD.
2) NleB GlcNAcylation of death domains blocked homotypic/heterotypic death domain interactions and assembly of the oligomeric TNFR1 complex which results in disrupting TNF signaling in EPEC-infected cells, including NFkB signaling, apoptosis, and necroptosis. 3) The arginine GlcNAc transferase activity of NleB is required for bacterial colonization in the mouse model of EPEC infection. |
