In enzymology, a trans-2-decenoyl-[acyl-carrier protein] isomerase () is an enzyme that catalyzes the chemical reaction
Hence, this enzyme has one substrate, trans-dec-2-enoyl-[acyl-carrier-protein], and one product, cis-dec-3-enoyl-[acyl-carrier-protein].
This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases transposing C=C bonds. The systematic name of this enzyme class is decenoyl-[acyl-carrier-protein] Delta2-trans-Delta3-cis-isomerase. Other names in common use include beta-hydroxydecanoyl thioester dehydrase, trans-2-cis-3-decenoyl-ACP isomerase, trans-2,cis-3-decenoyl-ACP isomerase, trans-2-decenoyl-ACP isomerase, and FabM.
