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. {ECO:0000255|HAMAP-Rule:MF_00405}.
