(3R)-3-hydroxymyristoyl-[acyl-carrier-protein] dehydratase activity

Definition

Target type: molecularfunction

Catalysis of the reaction: (3R)-3-hydroxytetradecanoyl-[acyl-carrier protein] = tetradecenoyl-[acyl-carrier protein] + H2O. [GOC:ai, PMID:12368867, RHEA:41892]

**(3R)-3-hydroxymyristoyl-[acyl-carrier-protein] dehydratase activity** catalyzes the removal of a water molecule from (3R)-3-hydroxymyristoyl-[acyl-carrier-protein], a key step in the biosynthesis of unsaturated fatty acids. This reaction is a dehydration, specifically a trans-enoyl-CoA hydratase activity. The enzyme facilitates the conversion of a hydroxyl group at the beta position of a fatty acyl chain to a double bond. The enzyme's active site contains a catalytic cysteine residue that forms a covalent adduct with the substrate. This adduct facilitates the removal of the water molecule, resulting in the formation of a trans-double bond. The reaction requires a cofactor, typically a divalent metal ion such as magnesium or manganese, to stabilize the catalytic cysteine and promote substrate binding.'
