Figure 1. Schematic Representation of the ATP Binding Site in KinasesATP (in ball-and-sticks) interacts mainly with the linker/adenine binding region (1), the ribose binding region (2), and the phosphate binding region (3). The two hydrophobic regions I (4) and II (5) do not directly interact with ATP and contain residues that vary among kinases, thus providing possibilities for the development of selective inhibitors [17]. Figures 1, 2B, and 3–6 were made with RIBBONS [42].
