10ACEUNKNOWNSER A:530SER 530 IS ACETYLATED BY ASPIRIN (AN ACETYL GROUP IS COVALENTLY ATTACHED TO THE PROTEIN WHEN INHIBITED WITH ASPIRIN). THE ACETYLATED SER PREVENTS THE PROPER BINDING OF THE SUBSTRATE IN THE CYCLOOXYGENASE ACTIVE SITE. IT HAS BEEN RECENTLY SHOWN, HOWEVER, THAT ACETYLATION OF CYCLOOXYGENASE-2 RESULTS IN THE FORMATION OF A DIFFERENT PRODUCT (15-HETE).

   Legend:   → Mismatch (orange background)
  - → Gap (green background, '-', border residues have a numbering label)
    → Modified Residue (blue background, lower-case, 'x' indicates undefined single-letter code, labelled with number + name)
  x → Chemical Group (purple background, 'x', labelled with number + name, e.g. ACE or NH2)
  extra numbering lines below/above indicate numbering irregularities and modified residue names etc., number ends below/above '|'
