Catalyzes the hydration of oleate at its cis-9-double bond to yield 10-hydroxyoctadecanoate. Cannot catalyze the reverse reaction. Is not active with saturated fatty acids and trans-, cis-5-, cis-6-, cis-8-, cis-11-, cis-13-, cis-14-, and cis-15-double bond unsaturated fatty acids as substrate, is only active on cis-9- and/or cis-12-double bond of unsaturated fatty acids without any trans-configurations, producing 10-hydroxy and 10,13-dihydroxy fatty acids. The hydration of unsaturated fatty acids is suggested to be a detoxification mechanism and a survival strategy for living in fatty acid-rich environments.
