PROSTAGLANDIN H2 SYNTHASE-1 COMPLEX WITH FLURBIPROFEN
OverviewOverview
The three-dimensional structure of prostaglandin H2 synthase-1, an, integral membrane protein, has been determined at 3.5 A resolution by, X-ray crystallography. This bifunctional enzyme comprises three, independent folding units: an epidermal growth factor domain, a, membrane-binding motif and an enzymatic domain. Two adjacent but spatially, distinct active sites were found for its haem-dependent peroxidase and, cyclooxygenase activities. The cyclooxygenase active site is created by a, long, hydrophobic channel that is the site of non-steroidal, anti-inflammatory drug binding. The conformation of the membrane-binding, motif strongly suggests that the enzyme integrates into only one leaflet, of the lipid bilayer and is thus a monotopic membrane protein.
