    • Homology modeling methods: hSMG-1 models were constructed using modeller (Eswar, N.; Marti-Renom, M. A.; Webb, B.; Madhusudhan, M. S.; Eramian, D.; Shen, M.; Pieper, U.; Sali, A. Curr. Protocols Bioinform. Suppl. 2006, 15, 5.6.1) with various PI3K structures as templates. Active site side chain positions were then reoptimized in the presence of an aminopyrimidine inhibitor using MacroModel with protocols similar to those described for docking. Initial models used unpublished PI3K-γ crystal structures from the same inhibitor series as PDB entry 3IBE. After solving 4FUL, models were rebuilt using 4FUL and 2RD0 as templates, and these models gave better results (tighter conformer clusters closer to the position observed for 2 bound to PI3K), possibly due to adjustments in the hinge and C-helix between 3IBE and 4FUL. Relative to PI3K-γ, hSMG-1 contains a ∼60-residue insertion in the kinase domain. The models did not include this region, but covered 220 residues of the kinase domain, of which 14 were judged insertions in hSMG-1 relative to PI3K-γ, 49 were conserved, and the remainder differed.
