This process calls for two enzymes [γ-glutamyl carboxylase (vitamin K–dependent carboxylase) and vitamin K epoxide reductase (vitamin K epoxide reductase complex subunit one, VKORC1), that are likely situated in shut proximity to each other inside the membrane with the endoplasmic reticulum62,79–81] and also carbon dioxide and oxygen. Proteins which can be undergoing γ-carboxylation incorporate a homologous sequence of about eighteen amino acids extended Positioned right away upstream on the carboxylated area. This area binds to the γ-glutamyl carboxylase and markedly facilitates the enzymatic reactions catalyzed by this enzyme. Interestingly, you will discover distinct affinities amongst the assorted vitamin K–dependent proproteins as well as enzyme, which might clarify some differences within their processing.75,seventy eight,eighty two VKORC1 will have to initial decrease vitamin K, which happens to be present in food items in its quinone variety.
