摘要：

The crystal structure of the membrane protein prostaglandin H synthase (PGHS) provides strong evidence for the existence of monotopic membrane proteins: PGHS seems to interact with the membrane via a motif of amphipathic helices positioned parallel to the plane of the membrane. The orientation of this unique membrane binding motif is fixed in space by an epidermial growth factor (EGF)-like module on its amino-terminal end and by the catalytic domain at its carboxy-terminal end. The catalytic domain of PGHS has a high structural homology to other mammalian heme peroxidases.
