Inhibitor binding mode ?
How is the binding mode derived?
KLIFS annotates the DFG/αC conformation and which (sub)pockets a ligand occupies; it does not store the inhibitor type. The mode shown here is derived from those annotations, so treat it as an approximation: Type I: DFG-in, ligand in the ATP site, back pocket empty; Type I½: DFG-in with back pocket occupied; Type II: DFG-out with back pocket occupied; Type III: back pocket occupied, front pocket empty; Allosteric: only an allosteric ligand outside the main pocket; Other: ligand-bound structures that fit none of these (e.g. DFG-out-like or αC/DFG not assigned); Apo: no ligand.
