SYSTEMATIC NAME
IUBMB Comments
peptidyl-glutamate 4-carboxylase (2-methyl-3-phytyl-1,4-naphthoquinone-epoxidizing)
The enzyme can use various vitamin-K derivatives, including menaquinol, but does not contain iron. The mechanism appears to involve the generation of a strong base by oxygenation of vitamin K. It catalyses the post-translational carboxylation of glutamate residues of several proteins of the blood-clotting system. 9--12 glutamate residues are converted to 4-carboxyglutamate (Gla) in a specific domain of the target protein. The 4-pro-S hydrogen of the glutamate residue is removed [5] and there is an inversion of stereochemistry at this position [6].

-
onset of mineralization in Abcc6-/-, Ggcx+/+ mice is delayed until between 3 and 4 months of age, suggesting that the genetic background plays a role in modifying the mineralization process. Mineralization in the Abcc6-/-, Ggcx+/- mice is accelerated in comparison with age-matched Abcc6-/-, Ggcx+/+ mice, with ca. 3fold difference at 3, 4, and 9 months of age

propeptide binding increases carboxylase affinity for the Glu substrate, and the coordinated binding of the vitamin K–dependent propeptide and Glu substrate increase carboxylase affinity for vitamin K and activity, possibly through a mechanism of substrate-assisted catalysis. The propeptide adjacent to the Gla domain is cleaved subsequently to carboxylation. The carboxylase uses the energy of vitamin K hydroquinone oxygenation to convert glutamyl residues to gamma-carboxylated glutamyl residues in vitamin K–dependent proteins. During carboxylation, the vitamin K hydroquinone cofactor is oxidized to a vitamin K epoxide product. The carboxylase itself is also a vitamin K–dependent protein and carboxylase carboxylation may be important in regulating the overall process of vitamin K–dependent protein carboxylation. All vitamin K–dependent proteins contain multiple glutamyl residues that undergo carboxylation, which is accomplished by a processive mechanism. A single binding event between carboxylase and vitamin K–dependent protein can give rise to all of the glutamyl to gamm-carboxylated glutamyl conversions in the vitamin K–dependent protein. Carboxylation is limited to the glutamyl residue residing within the Gla domain

vitamin K
-
carboxylation of FLEEL by bovine liver carboxylase is inhibited by high concentrations of vitamin KH2. vitamin K (up to 400 mM) and vitamin K epoxide (up to 1 mM) are not inhibitory. R234A/H235A mutant, R406A/H408A mutant, and R513A/K515A mutant are more susceptible to inhibition by vitamin KH2 than wild type enzyme. R234A/H235A mutant and R406A/H408A mutant exhibit maximal activity at 111 mM vitamin KH2 and R513A/K515A mutant at 56 mM vitamin KH2
