Notes de l'éditeur
- Hypothetical model of the vitamin K-dependent -carboxylation system. VKOR and -carboxylase are parts of a supramolecular assembly of proteins (the vitamin K-dependent -carboxylation system) in the endoplasmic reticulum (ER) membrane, and are responsible for the post-translational modification of vitamin K-dependent proteins. Reduced vitamin K 1 H 2 is produced by VKOR and is transferred to -carboxylase as an essential cofactor for -carboxylation. Calumenin binds to the supramolecular protein assembly as a chaperone and regulates the activity and warfarin sensitivity of the vitamin K-dependent -carboxylation system.
