title: Vitamin K-dependent carboxylation and vitamin K epoxidation. Evidence that the warfarin-sensitive microsomal NAD(P)H dehydrogenase reduces vitamin K1 in these reactions.
abstract: Passage of a Triton X-100-solubilized microsomal systems in vitro that are used to study these reactions is the warfarin-sensitive NAD(P)H dehydrogenase.
