Factor XIII is the fibrin-stabilizing factor that covalently cross-links fibrin monomers to form a highly organized, stable fibrin clot. The plasma form of factor XIII is a heterodimer, a2b2, consisting of two a-chains and two b-chains; the intracellular form, such as in platelets and placenta, is a dimer, a2, consisting of a-chains only. The catalytic function of factor XIII, a transglutaminas...

Transglutaminases are a family of enzymes that catalyze the formation of epsilon-(gamma-glutamyl)lysine isopeptide bonds in proteins, an activity that has been implicated in the pathogenesis of cartilage matrix mineralization in degenerative arthritis. Type II transglutaminase and thrombin-activatable factor XIII have been identified in articular cartilage. Thrombin, a coagulation protease, is ...

Factor XIII (F XIII) is an essential parameter for final clot stability. The purpose of this study was to determine the impact of the addition of factor (F)XIII on clot stability as assessed by Rotation Thromboelastometry (ROTEM). In 90 intensive care patients ROTEM measurements were performed after in vitro addition of F XIII 0.32 IU, 0.63 IU, 1.25 IU and compared to diluent controls (DC; aqua...

After communicating with the corresponding authors of “ESTHER, the database of the α/βhydrolase fold superfamily of proteins: tools to explore diversity of functions” [2], published in Nucleic Acids Research, the authors request to change the assignment of a new “family XV” described in our paper to an assignment of a new “subfamily XIII.2”. At the time of publication, “family XV” had already b...
