Wall-eyed stereo view of AA bound to the active
site of COX-1.
(A) A pocket formed by Phe-381, Leu-384, Trp-387, Phe-518, and Met-522
provides space for formation of the endoperoxide ring. (B) Tyr-348,
Phe-381, Typ-385, and Ser-530 surround carbon-15 of AA (green) dictating
the orientation of oxygen addition at this site. AA is colored by
element (with the exception of carbon-15 in B), and its surface is
shown as a mesh. Side chains of the residues indicated are displayed,
and their surface is shown in solid tan. From PDB 1DIY.
