Evolutionary conservation of the allosteric activation of factor VIIa by tissue factor in lamprey.

ABSTRACT: Essentials Tissue factor (TF) enhances factor VIIa (FVIIa) activity through structural and dynamic changes. We analyzed conservation of TF-activated FVIIa allosteric networks in extant vertebrate lamprey. Lamprey Tf/FVIIa molecular dynamics show conserved Tf-induced structural/dynamic FVIIa changes. Lamprey Tf activation of FVIIa allosteric networks follows molecular pathways similar to human.

Summary

Background Previous studies have provided insight into the molecular basis of human tissue factor (TF) activation of activated factor VII (FVIIa). TF-induced allosteric networks of FVIIa activation have been rationalized through analysis of the dynamic changes and residue connectivities in the human soluble TF (sTF)/FVIIa complex structure during molecular dynamics (MD) simulation.
