Abstract

Vitamin K is a cofactor specific to the vitamin K-dependent γ-glutamyl carboxylase and the formation of the amino acid γ-carboxyglutamic acid (Gla). Numerous Gla-containing proteins have been identified to date, including those involved in blood coagulation, but there are still significant gaps in knowledge about the physiological roles of many of these proteins.

Keywords:

  • vitamin K;
  • γ-carboxyglutamic acid;
