The simulation originating from the 1OG2 crystal structure in the absence of substrate will be referred to as 2C9_apo .
Two crystal structures, both obtained by Williams et al.,( 43 ) were used for the calculations on CYP2C9; the 1OG2 structure was used for simulating CYP2C9 in the absence of substrate, while the 1OG5 structure was used for all simulations containing the substrate S -warfarin.

Crystal structures of ligand-free CYP3A4 (PDB: 1TQN ) [ 10 ], CYP2C8 (PDB: 1PQ2 ) [ 11 ], and CYP2C9 (PDB: 1OG2 ) [ 12 ] were used as templates since their sequences were most similar to the target P4... 0s (14-33% primary sequence identity).
Template sequences of CYP3A4 (1TQN chain A), CYP2C9 (1OG2 chain A) and CYP2C8 (1PQN chain A) are aligned against target sequences CYP6AA3, CYP6P7 and CYP6P8.

Results Model Building The N-terminal sequence missing from the initial X-ray structure PDB ID 1OG2( 29 ) was modeled as an α-helix.
5 The X-ray structure of 1OG2 indicates the possible active site access paths, the solvent channel and the 2c channel (between the B′ and G helices).
Right panel shows RMSF per residue for simulations of wt CYP2C9 in membrane (black line), wt CYP2C9 in water (green line), CYP2C9 based on crystal structure 1OG2 (without N-terminal anchor) in water (red line), as well as RMSF calculated from the B-factors of crystals structures 1OG2 and 1OG5 (cyan and blue lines, respectively).
Materials and Methods Protein Model Building We used the crystal structure of ligand-free CYP2C9 (PDB ID 1OG2) as a template for model building.
Effects of the Membrane on the CYP Structure and Flexibility The RMSF profile calculated from the simulation of CYP2C9 based on 1OG2 X-ray structure agrees well with published results and displays the previously identified common flexible regions.
If the transmembrane segment is not present ( 1OG2 ), the prediction incorrectly exposes residues around the N-terminus to the solvent (Figure 5 , blue).
