CRYSTAL STRUCTURE OF ARACHIDONIC ACID BOUND IN THE CYCLOOXYGENASE ACTIVE SITE OF PGHS-1CRYSTAL STRUCTURE OF ARACHIDONIC ACID BOUND IN THE CYCLOOXYGENASE ACTIVE SITE OF PGHS-1
Structural highlights
FunctionPGH1_SHEEP May play an important role in regulating or promoting cell proliferation in some normal and neoplastically transformed cells. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedProstaglandin H synthase-1 and -2 (PGHS-1 and -2) catalyze the committed step in prostaglandin synthesis and are targets for nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin. We have determined the structure of PGHS-1 at 3 angstrom resolution with arachidonic acid (AA) bound in a chemically productive conformation. The fatty acid adopts an extended L-shaped conformation that positions the 13proS hydrogen of AA for abstraction by tyrosine-385, the likely radical donor. A space also exists for oxygen addition on the antarafacial surface of the carbon in the 11-position (C-11). While this conformation allows endoperoxide formation between C-11 and C-9, it also implies that a subsequent conformational rearrangement must occur to allow formation of the C-8/C-12 bond and to position C-15 for attack by a second molecule of oxygen. The productive conformation of arachidonic acid bound to prostaglandin synthase.,Malkowski MG, Ginell SL, Smith WL, Garavito RM Science. 2000 Sep 15;289(5486):1933-7.
