Compound as reactive (2)

oxidized dithiothreitol + 2-hydroxy-2-methyl-3-phytyl-2,3-dihydronaphthoquinone ← vitamin K 2,3-epoxide + L-dithiothreitol

oxidized dithiothreitol + 3-hydroxy-2-methyl-3-phytyl-2,3-dihydronaphthoquinone ← vitamin K 2,3-epoxide + L-dithiothreitol

Compound as product (1)

phylloquinone + a reduced electron donor + oxygen → an oxidized electron donor + H₂O + vitamin K 2,3-epoxide

Reversible reaction (2)

H₂O + oxidized dithiothreitol + 3-hydroxy-2-methyl-3-phytyl-2,3-dihydronaphthoquinone ↔ vitamin K 2,3-epoxide + L-dithiothreitol

phylloquinone + H₂O + oxidized dithiothreitol ↔ vitamin K 2,3-epoxide + L-dithiothreitol
