Title

(EN) HYBRID PROTEIN THAT CONVERTS ARACHIDONIC ACID INTO PROSTACYCLIN

Abstract

(EN)

A recombinant 130-kDa protein is constructed by linking together human cyclooxygenase (COX) isoform-2 (COX-2) and prostacyclin synthase (PGIS), via a 10-20 amino acid residues of a transmembrane sequence. The engineered protein is expressed in cells, and adopts the functions of COX and PGIS, to continually convert arachidonic acid (AA) into prostaglandin G₂(catalytic step 1), prostaglandin H₂(catalytic step 2) and prostacyclin (PGI₂; catalytic step 3).
