Functions
3-hydroxydecanoyl-[acyl-carrier-protein] dehydratase activity / 3-hydroxyoctanoyl-[acyl-carrier-protein] dehydratase activity / trans-2-decenoyl-acyl-carrier-protein isomerase activity
Processes
fatty acid biosynthetic process / lipid biosynthetic process
Components
cytosol
General Function
Necessary for the introduction of cis unsaturation into fatty acids. Catalyzes the dehydration of (3R)-3-hydroxydecanoyl-ACP to E-(2)-decenoyl-ACP and then its isomerization to Z-(3)-decenoyl-ACP. Can catalyze the dehydratase reaction for beta-hydroxyacyl-ACPs with saturated chain lengths up to 16:0, being most active on intermediate chain length. Is inactive in the dehydration of long chain unsaturated beta-hydroxyacyl-ACP.
