Figure 2. A structural analysis of CYP4V2 WT, MT1, and MT2. A: Homology model of WT- CYP4V2. B: Backbone superimposition of WT (cyan) with MT1 (Red), the altered secondary structures are shown in zoom view. C: Backbone superimposition of WT (cyan) with MT2 (Blue), the truncated region of MT2 in comparison with WT is shown in zoom view. D: Superimposed view of heme binding residues in WT (E329, C467) compared with MT1 (E329, C467). E: Superimposed view of heme binding residues in WT (E329, C467) compared with MT2 (E329). F, G, H: Electrostatic potential difference (scale: −2 to 2) in WT, MT1, and MT2, respectively. The blue color denotes a positive charge and red denotes a negative charge (the intensity of the shades are directly proportional to the charge levels).
