(A) View from the top of the trimeric complex. The structure was downloaded from the PDB database (3DWW). GSH is shown in ball and sticks. (B) Structural similarities between mPGES-1 (3DWW, in orange), and MGST-1 (2H8A.A, in cyan), FLAP (2Q7M.F, in cyan), Huntingtin interacting protein 12 or HIP-12 (1R0D.A, in cyan) and the protein tyrosine kinase 2 β or PTK2 (3GM3.A, in cyan).
