'''Human Factor Viia-Tissue Factor in Complex with peprid mimetic inhibitor that has two charge groups in P2 and P4'''<br />


==Overview==
==Human Factor Viia-Tissue Factor in Complex with peptide-mimetic inhibitor that has two charged groups in P2 and P4==
The crystal structure of human factor VIIa/soluble tissue factor, (FVIIa/sTF) in complex with a highly selective peptide-mimetic FVIIa, inhibitor which shows 1670-fold selectivity against thrombin inhibition, has been solved at 2.6 A resolution. The inhibitor is bound to FVIIa/sTF, at the S1, S2 and S3 sites and at the additional S1 subsite. Two charged, groups, the amidino group in P2 and the carboxylate group in P4, form, ionic interactions with Asp60 and Lys192 of FVIIa, respectively., Structural comparisons between factor VIIa and thrombin show that thrombin, has oppositely charged residues, Lys60F and Glu192, in the S2 site and the, S1 subsites, respectively. These data suggest that the utilization of the, differences of charge distribution in the S2 site and the S1 subsites, between FVIIa and thrombin is critical for achieving high selectivity, against thrombin inhibition. These results will provide valuable, information for the structure-based drug design of specific inhibitors for, FVIIa/TF.

[https://www.uniprot.org/uniprot/FA7_HUMAN FA7_HUMAN] Defects in F7 are the cause of factor VII deficiency (FA7D) [MIM:[https://omim.org/entry/227500 227500]. A hemorrhagic disease with variable presentation. The clinical picture can be very severe, with the early occurrence of intracerebral hemorrhages or repeated hemarthroses, or, in contrast, moderate with cutaneous-mucosal hemorrhages (epistaxis, menorrhagia) or hemorrhages provoked by a surgical intervention. Finally, numerous subjects are completely asymptomatic despite very low factor VII levels.<ref>PMID:8043443</ref> <ref>PMID:2070047</ref> <ref>PMID:1634227</ref> <ref>PMID:8364544</ref> <ref>PMID:8204879</ref> <ref>PMID:7981691</ref> <ref>PMID:7974346</ref> <ref>PMID:8652821</ref> <ref>PMID:8844208</ref> <ref>PMID:8940045</ref> <ref>PMID:8883260</ref> <ref>PMID:9414278</ref> <ref>PMID:9576180</ref> <ref>PMID:9452082</ref> <ref>PMID:11091194</ref> <ref>PMID:11129332</ref> <ref>PMID:10862079</ref> <ref>PMID:12472587</ref> <ref>PMID:14717781</ref> <ref>PMID:19751712</ref> <ref>PMID:18976247</ref> <ref>PMID:19432927</ref> <ref>PMID:21206266</ref> <ref>PMID:21372693</ref>
== Function ==
[https://www.uniprot.org/uniprot/FA7_HUMAN FA7_HUMAN] Initiates the extrinsic pathway of blood coagulation. Serine protease that circulates in the blood in a zymogen form. Factor VII is converted to factor VIIa by factor Xa, factor XIIa, factor IXa, or thrombin by minor proteolysis. In the presence of tissue factor and calcium ions, factor VIIa then converts factor X to factor Xa by limited proteolysis. Factor VIIa will also convert factor IX to factor IXa in the presence of tissue factor and calcium.

== Publication Abstract from PubMed ==
The crystal structure of human factor VIIa/soluble tissue factor (FVIIa/sTF) in complex with a highly selective peptide-mimetic FVIIa inhibitor which shows 1670-fold selectivity against thrombin inhibition has been solved at 2.6 A resolution. The inhibitor is bound to FVIIa/sTF at the S1, S2 and S3 sites and at the additional S1 subsite. Two charged groups, the amidino group in P2 and the carboxylate group in P4, form ionic interactions with Asp60 and Lys192 of FVIIa, respectively. Structural comparisons between factor VIIa and thrombin show that thrombin has oppositely charged residues, Lys60F and Glu192, in the S2 site and the S1 subsites, respectively. These data suggest that the utilization of the differences of charge distribution in the S2 site and the S1 subsites between FVIIa and thrombin is critical for achieving high selectivity against thrombin inhibition. These results will provide valuable information for the structure-based drug design of specific inhibitors for FVIIa/TF.
