Extended Data Fig. 8: Model of GGCX C-terminus self-carboxylation.
From: Structure and mechanism of vitamin-K-dependent γ-glutamyl carboxylase

a, The flexible C-terminus of GGCX (residues 726-758) is modeled into the center cavity of GGCX. Glu733, Glu757 and Glu748 are shown and Glu748 is modeled into the reaction center. MKH2-4, MK-4 hydroquinone. b, the top view of a.
