Probable 2' cyclic ADP-D-ribose synthase TcpB

UniProtKB accession:  C0RGW8

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Virulence factor that interferes with host Toll-like receptor 2 (TLR2) and TLR4 signaling, resulting in the reduction of dendritic cell maturation, inhibition of pro-inflammatory cytokine secretion and impaired NF-kappa-B activation in macrophages. Binds host lipids. Has NAD(+) hydrolase (NADase) activity, catalyzes cleavage of NAD(+) into ADP-D-ribose (ADPR) and nicotinamide, also generates a cyclization variant of cyclic ADPR (cADPR), termed v-cADPR (probably 2'cADPR).
