You see an affinity binding profile calculated for macromolecular interactions, where the maximal affinity is shown based on all measurements done with various molecule fragments, or modifications. To only show affinities of a specific fragment or functional site, select one on the top of the page. Be careful with the interpretation of the affinities found on this page. Always inspect the origin of the measured affinity value, as well as the results of additional experiments by clicking on the reported pKd value in the table.
