Biological process

Any process that increases the rate, frequency or extent of prostaglandin-endoperoxide synthase activity. Prostaglandin-endoperoxide synthase activity is the catalysis of the reaction: arachidonate + donor-H2 + 2 O2 = prostaglandin H2 + acceptor + H2O.

positive regulation of (PG)H synthase activity, positive regulation of PG synthetase activity, positive regulation of fatty acid cyclooxygenase activity, positive regulation of prostaglandin synthetase activity
