Transglutaminases: crosslinking enzymes with pleiotropic functions
Blood coagulation, skin-barrier formation, hardening of the fertilization envelope, extracellular-matrix assembly and other important biological processes are dependent on the rapid generation ofExpand

Transglutaminases and disease: lessons from genetically engineered mouse models and inherited disorders.
The human transglutaminase (TG) family consists of a structural protein, protein 4.2, that lacks catalytic activity, and eight zymogens/enzymes, designated factor XIII-A (FXIII-A) and TG1-7, thatExpand

Structural origins of fibrin clot rheology.
The origins of clot rheological behavior associated with network morphology and factor XIIIa-induced cross-linking were studied in fibrin clots. Network morphology was manipulated by varying theExpand

Mechanism of allosteric regulation of transglutaminase 2 by GTP
Allosteric regulation is a fundamental mechanism of biological control. Here, we investigated the allosteric mechanism by which GTP inhibits cross-linking activity of transglutaminase 2 (TG2), aExpand

Identification of a Novel Recognition Sequence for Fibronectin within the NH2-terminal β-Sandwich Domain of Tissue Transglutaminase*
Tissue transglutaminase belongs to the multigene transglutaminase family of Ca2+-dependent protein cross-linking enzymes. Unlike other transglutaminases, it is involved in cell-matrix interactionsExpand

Hydrolysis of γ:ε Isopeptides by Cytosolic Transglutaminases and by Coagulation Factor XIIIa*
Nε-(γ-glutamyl)lysine cross-links, connecting various peptide chain segments, are frequently the major products in transglutaminase-catalyzed reactions. We have now investigated the effectiveness ofExpand

Ca2+-related regulatory function of fibrinogen.
Fibrinogen displays a regulation of considerable physiological significance by lowering the Ca2+ requirement for the conversion of the fibrin-stabilizing factor (Factor XIII) zymogen to the range ofExpand

Affinity of human erythrocyte transglutaminase for a 42-kDa gelatin-binding fragment of human plasma fibronectin.
Complex formation between the human erythrocyte transglutaminase (protein-glutamine:amine gamma-glutamyltransferase, EC and fibronectin or its fragments was examined by immunoanalyticalExpand
