Figure 4: Stereo diagram of the models of AA (a) and PGH[2] ( b)
bound at the cyclooxygenase active site. Dashed lines
indicate hydrogen bonds or ion pairs formed. The double bonds of
the AA and PGH[2] are coloured blue. Protein side chains shown
are within van der Waals contact of the ligand. The C13
pro(S)-hydrogen (purple) and pro(R)-hydrogen (gold) of AA are
shown for reference.
