WebApr 1, 1995 · Together with a vitamin K-dependent carboxylase, carbon dioxide and molecular oxygen, vitamin K effects the carboxylation of selected glutamate residues in a number of proteins in the blood clotting sequence. These include: factor II (prothrombin), factor VII, factor IX, factor X and protein C, S and Z; as well as the bone protein osteocalcin. WebProthrombin is a multidomain vitamin-K-dependent zymogen that is converted to the active enzyme thrombin in the penultimate step of the coagulation cascade ().The multidomain assembly comprises an N-terminal Gla domain (residues 1–46), kringle 1 (residues 65–143), kringle 2 (residues 170–248), and a C-terminal protease domain (residues 285–579) …
