Application
Factor Xa chromogenic substrate has been used in factor Xa protease assay for placenta organelle protein and Prospirobolus joannsi.
Biochem/physiol Actions
Factor Xa chromogenic substrate contains peptide sequence Bz-Ile-Glu-Gly-Arg-pNA. Factor Xa mediates the release of p-NA chromogen post hydrolysis of substrate which is measurable photometrically.
Physical properties
KM for human factor Xa is ~0.8mM

Blood clot formation induced by dysfunctional coagulation is a frequent complication of coronavirus disease 2019 (COVID-19) and a high-risk factor for severe illness and death. Neutrophil extracellular traps (NETs) are implicated in COVID-19-induced immunothrombosis. Furthermore, human cathelicidin, a NET component

The repugnatorial glands of millipedes release various defensive chemical secretions. Although varieties of such defensive secretions have been studied, none of them is protein or peptide. Herein, a novel factor Xa (FXa) inhibitor named joannsin was identified and characterised from repugnatorial glands
