γ-Glutamyl carboxylase (GGCX) generates multiple carboxylated Glus (Glas) in vitamin K–dependent (VKD) proteins that are required for their functions. GGCX is processive, remaining bound to VKD proteins throughout multiple Glu carboxylations, and

The anticoagulant warfarin inhibits the vitamin K oxidoreductase (VKORC1), which generates vitamin K hydroquinone (KH2) required for the carboxylation and consequent activation of vitamin K-dependent (VKD) proteins. VKORC1 produces KH2 in 2 reactions
Vitamin K-dependent (VKD) protein activities require carboxylated Glus (Glas) generated by the gamma-glutamyl carboxylase. Some carboxylase mutations cause severe bleeding, while others cause pseudoxanthoma elasticum (PXE)-like associated with excess

Essentials A carboxylase mutation that impairs splicing to delete exon 2 sequences was previously reported. We found that the mutant was inactive for vitamin K-dependent (VKD) protein carboxylation. An incomplete splicing defect likely accounts for V

The vitamin K oxidoreductase (VKORC1) recycles vitamin K to support the activation of vitamin K-dependent (VKD) proteins, which have diverse functions that include hemostasis and calcification. VKD proteins are activated by Glu carboxylation, which d

The vitamin K oxidoreductase (VKOR) reduces vitamin K to support the carboxylation and consequent activation of vitamin K-dependent proteins, but the mechanism of reduction is poorly understood. VKOR is an integral membrane protein that reduces vitam

A characteristic feature of classic pseudoxanthoma elasticum (PXE), an autosomal recessive disorder caused by mutations in the ABCC6 gene, is aberrant mineralization of connective tissues, particularly the elastic fibers. Here, we report a family wit

Hereditary combined vitamin K–dependent (VKD) coagulation factor deficiency is an autosomal recessive bleeding disorder associated with defects in either the γ-carboxylase, which carboxylates VKD proteins to render them active, or the vitamin K ep

Leptospirosis is an emerging infectious disease whose pathology includes a hemorrhagic response, and sequencing of the Leptospira interrogans genome revealed an ortholog of the vitamin K-dependent (VKD) carboxylase as one of several hemostatic protei

Vitamin K-dependent (VKD) proteins are modified by the VKD carboxylase as they transit through the endoplasmic reticulum. In a reaction required for their activity, clusters of Glu's are converted to Gla's, and fully carboxylated VKD proteins are nor
