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}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a (3R)-hydroxyacyl-[ACP] = a (2E)-enoyl-[ACP] + H2O;
