In enzymology, a prostaglandin-F synthase (EC 1.1.1.188) is an enzyme that catalyzes the chemical reaction
- (5Z,13E)-(15S)-9alpha,11alpha,15-trihydroxyprosta-5,13-dienoate + NADP+ [math]\displaystyle{ \rightleftharpoons }[/math] (5Z,13E)-(15S)-9alpha,15-dihydroxy-11-oxoprosta-5,13-dienoate + NADPH + H+
Thus, the two substrates of this enzyme are (5Z,13E)-(15S)-9alpha,11alpha,15-trihydroxyprosta-5,13-dienoate and NADP+, whereas its 3 products are (5Z,13E)-(15S)-9alpha,15-dihydroxy-11-oxoprosta-5,13-dienoate, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (5Z,13E)-(15S)-9alpha,11alpha,15-trihydroxyprosta-5,13-dienoate:NADP+ 11-oxidoreductase. Other names in common use include prostaglandin-D2 11-reductase, reductase, 15-hydroxy-11-oxoprostaglandin, PGD2 11-ketoreductase, PGF2α synthetase, prostaglandin 11-ketoreductase, prostaglandin D2-ketoreductase, prostaglandin F synthase, prostaglandin F synthetase, synthetase, prostaglandin F2α, prostaglandin-D2 11-reductase, PGF synthetase, NADPH-dependent prostaglandin D2 11-keto reductase, and prostaglandin 11-keto reductase. This enzyme participates in arachidonic acid metabolism.
Structural studies
(As of 2007), 7 structures have been solved for this class of enzymes, with PDB accession codes 1RY0, 1RY8, 1VBJ, 1XF0, 1ZQ5, 2F38, and 2FGB.
