Web13 apr. 2013 · Koshland’s induced fit hypothesis suggests in the presence of the substrate the active site may change in order to fit the substrates change. The enzyme is flexible and molds to fit the substrate molecule like gloves fitting one’s hand or clothing on a person. The enzymes initially have a binding configuration which attracts the substrate. http://ecoursesonline.iasri.res.in/mod/page/view.php?id=9262

Web10 apr. 2024 · Koshland proposed this hypothesis in the year 1960. This hypothesis is actually quite different from the previous hypothesis. It states that the active site of the enzyme is flexible in shape and can change its shape according to the nature of the substrate, which means that it can form its active site complementary to the substrate. Web3 nov. 2006 · What Mesecar and Koshland [ 6] found was that the indentation was actually large relative to the ligand, so the three binding sites were in a crevice such that the binding sites could be approached from two directions.
