Claim: Linoleate diol synthase belongs to the family of chloroplasts, and the oxygen incorporated need not be derived from hydrogen monoxide, resulting in the end that the enzyme participates in mitosis.
Evidence: The oxygen incorporated need not be derived from O2. 
This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O2 as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases).
