In a calcium-dependent interaction critical for blood coagulation, vitamin K–dependent blood coagulation proteins bind cell membranes containing phosphatidylserine via γ-carboxyglutamic acid–rich (Gla) domains. Gla domain–mediated protein-membrane interaction is required for generation of thrombin, the terminal enzyme in the coagulation cascade, on a physiologic time scale. We determined by X-ray crystallography and NMR spectroscopy the lysophosphatidylserine-binding site in the bovine… Expand
Distinct structural and adhesive roles of Ca2+ in membrane binding of blood coagulation factors.
TLDR
The atomic model of a membrane-bound GLAdomain is presented by using MD simulations of the GLA domain of human factor VIIa and an anionic lipid bilayer and suggests that Ca2+ ions play two distinct roles in the process: the four inner Ca2- ions are primarily responsible for optimal folding of theGLA domain for membrane insertion, whereas the outer Ca2+, anchors the protein to the membrane through direct contacts with lipids.

Computational study of coagulation factor VIIa’s affinity for phospholipid membranes
TLDR
The MD simulation approach provides a structural and dynamic support to the role of P10Q and K32E mutations in the improvement of the membrane contact and a ranking of the rupture force that can be useful in the interpretation of the PS interaction with Gla domains is exhibited. Expand

TLDR
The fully carboxylated Gla domain of Factor IX is prepared by solid phase peptide synthesis and crystallized Factor IX-(1-47) in complex with Fab fragments of the 10C12 antibody and it is concluded that this antibody is directed at the membrane binding site in the ω loop offactor IX and blocks Factor IX function by inhibiting its interaction with membranes.

Selective modulation of protein C affinity for EPCR and phospholipids by Gla domain mutation
TLDR
Protein’C binding to sEPCR and phospholipids is broadly dependent on correct Gla domain folding, but can be selectively influenced by judicious mutation. Expand
Molecular Determinants of Phospholipid Synergy in Blood Clotting*
TLDR
It is proposed that phosphatidylcholine and sphingomyelin (the major external phospholipids of healthy cells) are anticoagulant primarily because their bulky choline headgroups sterically hinder access to their phosphates. Expand
Interaction of prothrombin with a phospholipid surface: evidence for a membrane-induced conformational change
TLDR
Data suggest that, on binding to a membrane surface, prothrombin undergoes a conformational change to a form which binds more tightly to the membrane. Expand
Lipid specificity of the membrane binding domain of coagulation factor X
TLDR
Molecular dynamics simulations were used to develop the first membrane‐bound model of FX‐GLA, and potential PS‐specific binding sites identified. Expand
Tissue factor/factor VIIa complex: role of the membrane surface.
TLDR
A combination of nanoscale membrane bilayers, solid-state NMR and all-atom molecular dynamics simulations are used, enabling detailed insights into how GLA domains bind to phospholipid bilayers and how specificospholipids enhance the catalytic activity of the TF:FVIIa complex. Expand
Multifunctional Specificity of the Protein C/Activated Protein C Gla Domain*
TLDR
Results reveal the specific Gla domain residues responsible for mediating protein C/APC molecular recognition with both its cofactor and receptor and further illustrate the multifunctional potential of Gla domains. Expand
The gamma-carboxyglutamic acid domain of anticoagulant protein S is involved in activated protein C cofactor activity, independently of phospholipid binding.
TLDR
By characterizing PS mutants in which PS face 1 and PS face 2 were individually replaced by the corresponding prothrombin faces, it is found that face 1 was necessary for efficient phospholipid binding but that face 2 residues were not strictly required for phospholIPid binding and were involved in the interaction with APC.

Identification of the Phospholipid Binding Site in the Vitamin K-dependent Blood Coagulation Protein Factor IX*
TLDR
Results indicate that the NH2 terminus of the Gla domain, specifically including leucine 6 and phenylalanine 9 in the hydrophobic patch, is the contact surface on Factor IX that interacts with the phospholipid bilayer. Expand
Vitamin K-dependent proteins.
TLDR
Special focus is on the structure-function role of Gla in blood coagulation and the impact of this amino acid on enzyme reaction kinetics and two proposed mechanisms of protein-membrane attachment are reviewed. Expand

TLDR
The crystal structure of X-bp in complex with the Gla domain peptide of factor X at 2.3-Å resolution showed that the anticoagulation is based on the fact that two patches of the GlA domain essential for membrane binding are buried in the complex formation. Expand

TLDR
The N-terminal noncatalytic Gla and EGF-like domains that provide the coagulation serine proteases with unique properties, such as affinity for certain biological membranes, and also mediate protein-protein interactions, are the subject of this review. Expand

Hydrophobic amino acid residues of human anticoagulation protein C that contribute to its functional binding to phospholipid Vesicles.
TLDR
It is proposed that the PL-dependent activity losses of these mutants are related to their suboptimal binding to PL or to their misorientation on the PL surface leading to poor alignment of the active sites of the r-APC mutants with the complementary cleavage sites on fVIII/fVIIIa and fV/fVa.

TLDR
Three‐dimensional structures of the Ca2+‐bound forms of the PKCα‐C2 domain both in the absence and presence of 1,2‐dicaproyl‐sn‐phosphatidyl‐L‐serine have been determined and suggest a membrane binding mechanism of the C2 domain in which calcium ions directly mediate the phosphate recognition while the calcium binding region 3 might penetrate into the phospholipid bilayer.
