CRYSTAL STRUCTURE OF THE COMPLEX BETWEEN THE COAGULATION FACTOR X BINDING PROTEIN FROM SNAKE VENOM AND THE GLA DOMAIN OF FACTOR X

Structural highlights

1iod is a 3 chain structure with sequence from Bos taurus and Deinagkistrodon acutus. The March 2006 RCSB PDB Molecule of the Month feature on Tissue Factor by David S. Goodsell is 10.2210/rcsb_pdb/mom_2006_3. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

SLUA_DEIAC Anticoagulant protein which binds to the gamma-carboxyglutamic acid-domain regions of factors IX (F9) and factor X (F10) in the presence of calcium with a 1 to 1 stoichiometry. Also inhibits platelet aggregation by binding to platelet glycoprotein Ibalpha (GP1BA) and functioning as a blocker of von Willebrand factor (VWF). Is devoid of hemorrhagic and lethal activities. Possesses antithrombotic and thrombolytic activities. Also hydrolyzes the Aalpha-chain of fibrinogen (FGA). Does not affect the Bbeta-chain (FGB) and the gamma chain (FGG).^[1] ^[2] ^[3]

-== Publication Abstract from PubMed ==
-The gamma-carboxyglutamic acid (Gla) domain of blood coagulation factors is responsible for Ca2+-dependent phospholipid membrane binding. Factor X-binding protein (X-bp), an anticoagulant protein from snake venom, specifically binds to the Gla domain of factor X. The crystal structure of X-bp in complex with the Gla domain peptide of factor X at 2.3-A 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. The Gla domain thus is expected to be a new target of anticoagulant drugs, and X-bp provides a basis for designing them. This structure also provides a membrane-bound model of factor X.
