Which of the following vitamin dependent carboxylase is found in the liver?

Vitamin K functions as an essential cofactor for the enzyme γ-glutamyl carboxylase in the liver. This carboxylation process converts specific glutamate residues on blood clotting proteins (like prothrombin, Factors VII, IX, and X) into γ-carboxyglutamate, enabling them to bind calcium and execute the coagulation cascade.
