WebJun 19, 2016 · The difference is that imatinib binds to (and blocks) the pocket where normally the phosphate groups of ATP bind, forcing Abl (and Abl-BCR) into a conformation that is similar to the inactive state. The drug can still bind to the active state but upon binding, Abl changes its conformation and then looks similar to the inactive state. WebWithout its substrate, the inactive conformation A is one thousand times more populated than the active conformation B. When the substrate is present, on the other hand, the active conformation B is one million times more populated. Please determine the free energy difference between A and B without and with presence of the substrate.
