ProteomicsMolecular basis of vitamin K driven γ-carboxylation at membrane interface
The γ-carboxylation of glutamate residues enables Ca2+-mediated membrane assembly of protein complexes that support broad physiological functions including hemostasis, calcium homeostasis, immune response, and endocrine regulation. Modulating γ-carboxylation level provides prevalent treatments for h...

ProteomicsStructural mechanism of γ-carboxylation coupled to vitamin K epoxidation at membrane interface
Hemostasis and various non-hemostatic physiologies require γ-carboxylation of designated glutamates in vitamin K-dependent proteins (VKDPs), a process coupled with epoxidation of vitamin K hydroquinone (KH2) by membrane-integrated γ-carboxylase (VKGC). To understand this unique biochemistry, we dete...
