In enzymology, a 3-oxoacyl-[acyl-carrier-protein] reductase (EC 1.1.1.100) is an enzyme that catalyzes the chemical reaction

3-oxoacyl-[acyl-carrier-protein](ACP) + NADPH + H+ (3R)-3-hydroxyacyl-[acyl-carrier-protein](ACP) + NADP+
3-oxoacyl-ACP reductase reaction.svg

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group as hydride donor with NAD+ or NADP+ as hydride acceptor. The systematic name of this enzyme class is (3R)-3-hydroxyacyl-[acyl-carrier-protein]:NADP+ oxidoreductase. Other names in common use include beta-ketoacyl-[acyl-carrier protein](ACP) reductase, beta-ketoacyl acyl carrier protein (ACP) reductase, beta-ketoacyl reductase, beta-ketoacyl thioester reductase, beta-ketoacyl-ACP reductase, beta-ketoacyl-acyl carrier protein reductase, 3-ketoacyl acyl carrier protein reductase, 3-ketoacyl ACP reductase, NADPH-specific 3-oxoacyl-[acylcarrier protein]reductase, and 3-oxoacyl-[ACP]reductase. This enzyme participates in fatty acid biosynthesis and polyunsaturated fatty acid biosynthesis.

<span class="mw-page-title-main">Fatty-acyl-CoA synthase</span>

Fatty-acyl-CoA synthase, or more commonly known as yeast fatty acid synthase, is an enzyme complex responsible for fatty acid biosynthesis, and is of Type I Fatty Acid Synthesis (FAS). Yeast fatty acid synthase plays a pivotal role in fatty acid synthesis. It is a 2.6 MDa barrel shaped complex and is composed of two, unique multi-functional subunits: alpha and beta. Together, the alpha and beta units are arranged in an α6β6 structure. The catalytic activities of this enzyme complex involves a coordination system of enzymatic reactions between the alpha and beta subunits. The enzyme complex therefore consists of six functional centers for fatty acid synthesis.

<span class="mw-page-title-main">Ketoacyl synthase</span> Catalyst for a key step in fatty acid synthesis

Ketoacyl synthases (KSs) catalyze the condensation reaction of acyl-CoA or acyl-acyl ACP with malonyl-CoA to form 3-ketoacyl-CoA or with malonyl-ACP to form 3-ketoacyl-ACP. This reaction is a key step in the fatty acid synthesis cycle, as the resulting acyl chain is two carbon atoms longer than before. KSs exist as individual enzymes, as they do in type II fatty acid synthesis and type II polyketide synthesis, or as domains in large multidomain enzymes, such as type I fatty acid synthases (FASs) and polyketide synthases (PKSs). KSs are divided into five families: KS1, KS2, KS3, KS4, and KS5.

Elongase is a generic term for an enzyme that extends the length of fatty acid. The nomenclature is not applied rigorously. Often, elongase refers to enzymes that produce very long chain fatty acids. Sometimes, elongase also includes unsaturases, which introduce C=C double bonds in the backbone. Because fatty acids and their derivatives are biochemically influential, elongases are of considerable interest.
