Clostridium botulinum - an overview ScienceDirect Topics
WebThe C2 toxin of Clostridium botulinum is a binary bacterial protein toxin, comprising the enzyme component C2I and the separate binding/translocation component C2IIa. C2IIa mediates the transport of C2I into the host cell cytosol. The N-terminal domain of C2I (C2IN) is enzymatically inactive but essential for C2IIa-mediated internalization of C2I. Here, we … WebClostridium botulinum is a Gram-positive, anaerobic, rod-shaped, spore-forming bacterium that produces the most potent biological toxin known, botulinum neurotoxin. Strains of C. botulinum are separated into seven types, A through G, based on the serological specificity of the neurotoxin produced. seve dans l\u0027oeil
