3-hydroxydecanoyl-(acyl-carrier-protein) dehydratase (EC, D-3-hydroxydecanoyl-[acyl-carrier protein] dehydratase, 3-hydroxydecanoyl-acyl carrier protein dehydrase, 3-hydroxydecanoyl-acyl carrier protein dehydratase, beta-hydroxydecanoyl thioester dehydrase, beta-hydroxydecanoate dehydrase, beta-hydroxydecanoyl thiol ester dehydrase, FabA, beta-hydroxyacyl-acyl carrier protein dehydratase, HDDase, beta-hydroxyacyl-ACP dehydrase, (3R)-3-hydroxydecanoyl-[acyl-carrier-protein] hydro-lyase) is an enzyme with systematic name (3R)-3-hydroxydecanoyl-(acyl-carrier protein) hydro-lyase.[1][2][3][4][5][6][7] This enzyme catalyses the following chemical reaction

(1) a (3R)-3-hydroxydecanoyl-[acyl-carrier protein] a trans-dec-2-enoyl-[acyl-carrier protein] + H2O
(2) a (3R)-3-hydroxydecanoyl-[acyl-carrier protein] a cis-dec-3-enoyl-[acyl-carrier protein] + H2O

This enzyme is specific for C10 chain length.
