GGCX (gamma glutamyl carboxylase) in the endoplasmic reticulum gamma-carboxylates three glutamate residues on BGLAP(24-100) (pro-osteocalcin). MK4 (vitamin K hydroquinone) is oxidized to MK4 epoxide in the process (Berkner 2000; Ferron et al. 2015; Furie et al. 1999; Hauschka et al. 1989; Morris et al. 1995; oser et al. 1980; Stenina et al. 2001).
