Protein necessary for clot formation
Webb6 mars 2024 · A pro-clotting factor found in the blood, vitamin K is necessary for an important modification to prothrombin and other blood clotting proteins. Vitamin K serves as an enzyme cofactor that helps to catalyze addition of an extra carboxyl group onto the side chain of glutamic acid residues of several clotting enzymes (see HERE). WebbBlood-clotting proteins generate thrombin, an enzyme that converts fibrinogen to fibrin, and a reaction that leads to the formation of a fibrin clot. The hemostatic mechanism involves three physiologically important reactions: (1) the formation of a blood clot , (2) the formation of a platelet plug, and (3) changes associated with the wall of the blood vessel …
