Literature summary extracted from
- Inactivation of active thrombin-activable fibrinolysis inhibitor takes place by a process that involves conformational instability rather than proteolytic cleavage (2000), J. Biol. Chem., 275, 12410-12415.

| 3.4.17.20 | R302Q | specific activity with hippuryl-Arg is approximately half that of either recombinant wild-type enzyme or plasma derived enzymeR302Q-TAFIa is not proteolyzed by thrombin, even when 10times higher concentrations of thrombin/thrombomodulin are used | Homo sapiens |
General Stability
| EC Number | General Stability | Organism |
|---|---|---|
| 3.4.17.20 | inactivation of TAFIa is the result of the conformational instability of TAFIa and not a direct result of proteolysis of TAFIa. It is possible that the conformational changes that take place as a result of the conformational instability make the inactivated 35800 Da enzyme form more susceptible to proteolysis. epsilon-Aminocaproic acid stabilizes | Homo sapiens |
