Tetanus toxin C-fragment structure
Tetanus toxin C-fragment, molecular model. This is a fragment of the neurotoxin protein produced by the bacterium Clostridium tetani that causes tetanus. This fragment is responsible for binding to lipids on the membranes of nerve cells (gangliosides). Once bound, other fragments of the protein use enzymatic properties to enter the cell. The toxin prevents the release of inhibitory neurotransmitters from the nerve cells, leading to muscle overactivity, or spasms. In this model the coils and arrows (solid colours) represent the proteins secondary structure, and the tubular structure behind (faded colours) shows individual atoms and bonds

EDITORS COMMENTS
This print showcases the intricate structure of the Tetanus toxin C-fragment, a vital component of the neurotoxin protein produced by Clostridium tetani bacteria. Responsible for causing tetanus, this fragment plays a crucial role in binding to lipids on nerve cell membranes known as gangliosides. Once bound, other fragments of the protein utilize their enzymatic properties to enter these cells. The consequences of this invasion are profound - inhibitory neurotransmitters are prevented from being released from nerve cells, resulting in muscle overactivity and spasms. The visual representation presented here offers an insightful glimpse into the molecular world that underlies such debilitating effects. In this model, we can observe how coils and arrows with solid colors depict the secondary structure of proteins while faded colors reveal individual atoms and bonds within the tubular formation behind them. This comprehensive illustration not only highlights its biological significance but also integrates elements from various scientific disciplines including biology, medicine, chemistry, bacteriology, biochemistry, and microbiology. By capturing this molecular model with precision and clarity, Science Photo Library provides us with a valuable tool for understanding both the complexity and beauty inherent in nature's smallest building blocks.
