| Post Translational Modification | PTM: The gamma-carboxyglutamyl residues, which bind calcium ions, result from the carboxylation of glutamyl residues by a microsomal enzyme, the vitamin K-dependent carboxylase. The modified residues are necessary for the calcium-dependent interaction with a negatively charged phospholipid surface, which is essential for the conversion of prothrombin to thrombin. {ECO:0000269|PubMed:3759958, ECO:0000269|PubMed:6305407}.; PTM: N-glycosylated.
