In enzymology, a 15-oxoprostaglandin 13-oxidase (EC 1.3.1.48) is an enzyme that catalyzes the chemical reaction

(5Z)-(15S)-11alpha-hydroxy-9,15-dioxoprostanoate + NAD(P)+ (5Z)-(15S)-11alpha-hydroxy-9,15-dioxoprosta-13-enoate + NAD(P)H + H+

The 3 substrates of this enzyme are (5Z)-(15S)-11alpha-hydroxy-9,15-dioxoprostanoate, NAD+, and NADP+, whereas its 4 products are (5Z)-(15S)-11alpha-hydroxy-9,15-dioxoprosta-13-enoate, NADH, NADPH, and H+.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (5Z)-(15S)-11alpha-hydroxy-9,15-dioxoprostanoate:NAD(P)+ Delta13-oxidoreductase. Other names in common use include 15-oxo-Delta13-prostaglandin reductase, Delta13-15-ketoprostaglandin reductase, 15-ketoprostaglandin Delta13-reductase, prostaglandin Delta13-reductase, prostaglandin 13-reductase, and 15-ketoprostaglandin Delta13-reductase.

Structural studies

As of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes 1V3T, 1V3U, 1V3V, and 2DM6.

5-Hydroxyeicosanoid dehydrogenase (5-HEDH) or more formally, nicotinamide adenine dinucleotide phosphate (NADP+)-dependent dehydrogenase, is an enzyme that metabolizes an eicosanoid product of arachidonate 5-lipoxygenase (5-LOX), 5(S)-hydroxy-6S,8Z,11Z,14Z-eicosatetraenoic acid (i.e. 5-(S)-HETE; see 5-HETE) to its 5-keto analog, 5-oxo-eicosatetraenoic acid (i.e. 5-oxo-6S,8Z,11Z,14Z-eicosatetraenoic acid or 5-oxo-ETE). It also acts in the reverse direction, metabolizing 5-oxo-ETE to 5(S)-HETE. Since 5-oxo-ETE is 30–100-fold more potent than 5(S)-HETE in stimulating various cell types, 5-HEDH is regarded as a regulator and promoter of 5(S)HETE's and thereby 5-LOX's influences on cell function. Although 5-HEDH has been evaluated in a wide range of intact cells and in crude microsome preparations, it has not yet been evaluated for its structure, for its gene, of in pure form; furthermore, most studies on it have been conducted in human tissues.
