CC -!- FUNCTION: Necessary for the introduction of cis unsaturation into fatty
CC acids. Catalyzes the dehydration of (3R)-3-hydroxydecanoyl-ACP to E-
CC (2)-decenoyl-ACP and then its isomerization to Z-(3)-decenoyl-ACP. Can
CC catalyze the dehydratase reaction for beta-hydroxyacyl-ACPs with
CC saturated chain lengths up to 16:0, being most active on intermediate
CC chain length (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a (3R)-hydroxyacyl-[ACP] = a (2E)-enoyl-[ACP] + H2O;

CC ChEBI:CHEBI:78467, ChEBI:CHEBI:78798; EC=5.3.3.14;
CC -!- PATHWAY: Lipid metabolism; fatty acid biosynthesis.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the thioester dehydratase family. FabA
CC subfamily. {ECO:0000305}.
