In enzymology a vitamin-K-epoxide reductase (warfarin-sensitive) (EC 1.1.4.1) is an enzyme that catalyzes the chemical reaction2-methyl-3-phytyl-14-naphthoquinone + oxidized dithiothreitol 23-epoxy-23-dihydro-2-methyl-3-phytyl-14-naphthoquinone + 14-dithiothreitolThus the two substrates of this enzyme are 2-methyl-3-phytyl-14-naphthoquinone and oxidized dithiothreitol whereas its two products are 23-epoxy-23-dihydro-2-methyl-3-phytyl-14-naphthoquinone and 14-dithiothreitol.This enzyme belongs to the family of oxidoreductases specifically those acting on the CH-OH group of donor with a disulfide as acceptor.
