In enzymology, a 15-hydroxyicosatetraenoate dehydrogenase (EC 1.1.1.232) is an enzyme that catalyzes the chemical reaction

(15S)-15-hydroxy-5,8,11-cis-13-trans-icosatetraenoate + NAD(P)+ 15-oxo-5,8,11-cis-13-trans-icosatetraenoate + NAD(P)H + H+

The 3 substrates of this enzyme are 15-hydroxyicosatetraenoic acid (i.e. 15(S)-15-hydroxy-5,8,11-cis-13-trans-icosatetraenoate), NAD+, and NADP+, whereas its 4 products are 15-oxo-5,8,11-cis-13-trans-icosatetraenoate, NADH, 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 (15S)-15-hydroxy-5,8,11-cis-13-trans-icosatetraenoate:NAD(P)+ 15-oxidoreductase. This enzyme is also called 15-hydroxyeicosatetraenoate dehydrogenase. This enzyme participates in arachidonic acid metabolism.

<span class="mw-page-title-main">Aspartate-semialdehyde dehydrogenase</span> Amino-acid-synthesizing enzyme in fungi, plants and prokaryota

In enzymology, an aspartate-semialdehyde dehydrogenase is an enzyme that is very important in the biosynthesis of amino acids in prokaryotes, fungi, and some higher plants. It forms an early branch point in the metabolic pathway forming lysine, methionine, leucine and isoleucine from aspartate. This pathway also produces diaminopimelate which plays an essential role in bacterial cell wall formation. There is particular interest in ASADH as disabling this enzyme proves fatal to the organism giving rise to the possibility of a new class of antibiotics, fungicides, and herbicides aimed at inhibiting it.

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.
