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   -!- 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}.
