Actinidin

thingiverse

Actinidin, also known as actinidain or Actinidia anionic protease, is a cysteine protease found in Kiwi fruit (Actinidia chinensis). It plays a crucial role in the fruit's defense mechanism. This enzyme breaks down proteins into smaller peptides, making it an essential component of the fruit's immune system. The STL file provided offers a three-dimensional representation of actinidin in cartoon form, highlighting its catalytic residues as spheres. Additionally, cysteine disulfide bonds are visualized as spheres, providing valuable insights into the protein's structure and function. The model is based on data from the Protein Data Bank entry 2ACT. Actinidin was modeled using VMD, a powerful software tool for molecular visualization and analysis. This tool allows researchers to explore the intricate details of proteins like actinidin, shedding light on their mechanisms and properties. By studying actinidin's structure and function, scientists can gain a deeper understanding of its role in Kiwi fruit and its potential applications in various fields.
