Abstract excerpt
Coagulation factor XIII (FXIII) proenzyme circulates in plasma as a heterotetramer composed of two each of A and B subunits. Upon activation, the B subunits dissociate from the A subunit dimer, which gains transglutaminase activity to cross-link preformed fibrin clots increasing mechanical strength and resistance to degradation. The B subunits are thought to possess a carrier/protective function before FXIII...
