متن کاملA rho gene product in human blood platelets. II. Effects of the ADP-ribosylation by botulinum C3 ADP-ribosyltransferase on platelet aggregation.
In the accompanying paper (Nemoto, Y., Namba, T., Teru-uchi, T., Ushikubi, F., Morii, N., and Narumiya, S. (1992) J. Biol. Chem. 267, 20916-20920), we have identified rhoA protein as the sole substrate protein for botulinum C3 ADP-ribosyltransferase (C3 exoenzyme) in human blood platelets. Here we examined the role of rhoA protein in platelet functions. C3 exoenzyme added to washed platelets do...
متن کاملADP-ribosylation of a 21-24 kDa eukaryotic protein(s) by C3, a novel botulinum ADP-ribosyltransferase, is regulated by guanine nucleotide.
Besides botulinum C2 toxin, Clostridium botulinum type C produces another ADP-ribosyltransferase, which we termed 'C3'. ADP-ribosyltransferase C3 has a molecular mass of 25 kDa and modifies 21-24 kDa protein(s) in platelet and brain membranes. C3 was about 1000 times more potent than botulinum C1 toxin in ADP-ribosylation of membrane proteins. C3-catalysed ADP-ribosylation of the 21-24 kDa prot...
متن کاملEngineering Botulinum Neurotoxin C1 as a Molecular Vehicle for Intra-Neuronal Drug Delivery
Botulinum neurotoxin (BoNT) binds to and internalizes its light chain into presynaptic compartments with exquisite specificity. While the native toxin is extremely lethal, bioengineering of BoNT has the potential to eliminate toxicity without disrupting neuron-specific targeting, thereby creating a molecular vehicle capable of delivering therapeutic cargo into the neuronal cytosol. Building upo...
متن کاملIdentification of a novel botulinum neurotoxin gene cluster in Enterococcus
The deadly neurotoxins of Clostridium botulinum (BoNTs) comprise eight serotypes (A-G; X). The neurotoxin gene cluster encoding BoNT and its accessory proteins includes an operon containing an ntnh gene upstream of the boNT gene. Another operon contains either ha (haemagglutinin) or orfX genes (of unknown function). Here we describe a novel boNT gene cluster from Enterococcus sp. 3G1_DIV0629, w...
