Structural Analysis EGFR crystal structures (PDB accession codes 1M17, 1XKK and 2GS6) ( Stamos et al. , 2002 ; Wood et al. , 2004 ; Zhang et al. , 2006 ) were analyzed using the program O ( Jones et a... . , 1991 ).

Hierarchical modeling of activation mechanisms in the ABL and EGFR kinase domains: thermodynamic and mechanistic catalysts of kinase activation by cancer mutations.

Materials and Methods Structure Preparation In simulations of the ABL and EGFR kinase domains, we used the following crystal structures from the Protein Data Bank (PDB): pdb entry 1IEP (inactive ABL s... ructure), pdb entry 2G1T (Src-like inactive ABL structure), pdb entry 1M52 (active ABL structure), pdb entry 1XKK (Src/Cdk-like inactive EGFR structure), pdb entry 2GS7 (Src/Cdk-like inactive EGFR structure) and pdb entry 2J6M (active EGFR structure).

The crystal structures of EGFR represent the following conformational forms: the Lapatinib-bound, inactive structure (pdb entry 1XKK) (A), the Src/Cdk-like inactive structure (pdb entry 2GS7) (B), and the active structure (pdb entry 2J6M) (C).

Similarly, TMD simulations were carried out for EGFR-WT, EGFR-T790M and EGFR-L858R to model conformational transitions between the Src/Cdk-like inactive form of EGFR (pdb entry 1XKK) and the target active EGFR form (pdb entry 2J6M for EGFR-WT; pdb entry 2JIU for EGFR-T790M; and pdb entry 2ITT for EGFR-L858R).

Similarly, MD simulations of the EGFR kinase domain were initiated for EGFR-WT, EGFR-T790M, EGFR-L858R from the Src/Cdk-like inactive structures (pdb entries 1XKK, 2GS7), and active conformational form (pdb entry 2G6M).

The structure of 1XKK is unresolved for residues 749–754 (activation loop) and residues 867–876 (αC-helix), thus the unresolved parts were modeled using the program MODELLER which is an automated approach to comparative protein structure modeling by satisfaction of spatial restraints [95] , [96] .

A) Superposition of the C-terminal tail in the active (PDB: 2JIU), inactive monomer (PDB: 1XKK) and inactive dimer (PDB: 3GT8).

Three functional states of EGFR are used (active dimer based upon PDB: 3GOP), inactive dimer (based upon PDB: 3GT8) and inactive monomer (based upon PDB: 1XKK) to illustrate the coordinated functions of the identified residues in kinase activation.

The AST is typically disordered in most ErbB structures; however, in two structures of EGFR (PDB:1XKK and 2JIU) [19] , [53] , the AST segment adopts two distinct conformations.

Allosteric Signatures of Mutation-Induced EGFR Activation In this section, we analyzed allosteric signatures of the EGFR kinase catalytic domain using the results of MD simulations in the following fu... ctional states: the inactive EGFR form (PDB ID 1XKK) [77] ; the active EGFR form (PDB ID 2J6M) [78] , the active form of the EGFR-T790M mutant (PDB ID 2JIT) [79] .

In MD simulations of the ABL and EGFR kinase domains, we used the following crystal structures : PDB ID 1IEP (inactive ABL structure) [70] , PDB ID 1M52 (active ABL structure) [71] , [72] , PDB ID 2G1T (Src-like inactive ABL structure) [109] , PDB ID 2Z60 (the active form of the ABL-T315I mutant) [75] , PDB ID 1XKK (Src/Cdk-like inactive EGFR structure) [77] , PDB ID 2GS7 (Src/Cdk-like inactive EGFR structure) [109] , and PDB ID 2J6M (active EGFR structure) [78] , and PDB ID 2JIT (EGFR-T790M mutant) [79] .

The analysis was performed using inhibitor-bound crystal structures of EGFR in the inactive form (PDB ID 1XKK) [ 117 ] and active form (PDB ID 2J6M) [ 118 ] .

The analysis was performed on the unbound form of the crystal structures of EGFR in the inactive form (PDB ID 1XKK) [ 117 ] and active form (PDB ID 2J6M) [ 118 ] .

We observed that highly oncogenic mutations may indeed cause an increase in the local frustration of mutated residues in the inactive autoinhibitory state of ABL (PDB ID 1IEP) [ 90 ] and EGFR (PDB ID 1XKK) [ 117 ] ( Figures 3 , 4 ).

W3–W5 in the erlotinib complex structure lie in a pocket occupied by the (3-fluorobenzyl)oxy group of lapatinib in PDB entry 1XKK.

Surprisingly, docking erlotinib into a crystal structure of the inactive EGFR-TKD (PDB entry 1XKK [ 13 ]), after removing lapatinib from the model, yielded a very similar Glide [ 32 ] score (−9.72 kcal/mol) to that seen for active EGFR-TKD (−9.34 kcal/mol).

As shown in Figure 2 , our structure of inactive EGFR-TKD closely resembles that seen in PDB entry 1XKK [ 13 ] (in complex with lapatinib).

Interestingly, as shown in Figure 3 (B), waters W3–W5 in our structure lie in the same pocket within inactive EGFR-TKD that is occupied by the (3-fluorobenzyl)oxy group of lapatinib in PDB entry 1XKK [ 13 ]; these waters also interact with the EGFR-TKD backbone in parts of the αC helix (Met 742 ) and Phe 832 of the DFG motif.

Inactive EGFR-TKD was modelled based on PDB entries 2GS7 [ 12 ] and 1XKK [ 13 ].

( B ) The mode of erlotinib binding to inactive EGFR-TKD observed crystallographically (green) is compared with the mode of lapatinib binding to inactive EGFR-TKD in PDB entry 1XKK [ 13 ] (grey), in a view rotated by 180° about a vertical axis compared with that seen in ( A ).

Crystal structures of the kinase domain of EGFR with either erlotinib (1M17) 15 or lapatinib (1XKK) 9 (Figure 1 A,B) show that while the pharmacophore arm is oriented deep in the binding pocket, the 6-position is amenable to chemical modification without perturbing the key conserved contacts of the binding pocket.
