Identification of a guanosine triphosphate-binding site on guinea pig liver transglutaminase. Role of GTP and calcium ions in modulating activity.
Guanosine 5'-triphosphate (GTP) was found to inhibit guinea pig liver transglutaminase activity as measured by [3H]putrescine incorporation into casein. GDP and GTP-gamma-S also inhibited enzymeExpand
A microtiter plate transglutaminase assay utilizing 5-(biotinamido)pentylamine as substrate.
Transglutaminases belong to an important family of enzymes involved in hemostasis, skin formation, and wound healing. We describe a technique for the measurement of transglutaminase activity usingExpand
Supramolecular self-assembled chaos: polyphenolic lignin's barrier to cost-effective lignocellulosic biofuels.
Phenylpropanoid metabolism yields a mixture of monolignols that undergo chaotic, non-enzymatic reactions such as free radical polymerization and spontaneous self-assembly in order to form theExpand
Comparative enzymology, biochemistry and pathophysiology of human exo-α-sialidases (neuraminidases)
Abstract This review summarizes the current research on human exo -α-sialidase (sialidase, neuraminidase). Where appropriate, the properties of viral, bacterial, and human sialidases have beenExpand
Factor XIIIa-derived peptides inhibit transglutaminase activity. Localization of substrate recognition sites.
Factor XIIIa is a transglutaminase that catalyzes intermolecular gamma-glutamyl-epsilon-lysyl bonds between fibrin and other proteins involved in hemostasis. We synthesized 25 peptides from variousExpand
The binding of divalent metal ions to platelet factor XIII modulates its proteolysis by trypsin and thrombin.
We investigated the effect of divalent metal ions on the proteolytic cleavage and activation of platelet Factor XIII by thrombin and trypsin. In the absence of metal ions (5 mM EDTA), trypsin andExpand
Biocidal activity of a light-absorbing fluorescent conjugated polyelectrolyte.
Herein we describe studies that indicate a cationic conjugated polyelectrolyte shows biocidal activity against gram-negative bacteria (Escherichia coli, E. coli, BL21, with plasmids for Azurin andExpand
Carboxyl-terminal truncation of recombinant factor XIII A-chains. Characterization of minimum structural requirement for transglutaminase activity.
A series of truncation mutants lacking 218, 229, 250, and 269 amino acid residues from the carboxyl terminus of blood coagulation factor XIII A-chains (FXIII A), designated as delta K513, delta A502,Expand
Vitronectin is a substrate for transglutaminases.
Vitronectin (VN) was found to be a substrate for both plasma transglutaminase (Factor XIIIa) and guinea pig liver transglutaminase (TG). Incorporation of [3H]-putrescine indicated the presence ofExpand
Characterization of the fibrin polymer structure that accelerates thrombin cleavage of plasma factor XIII.
The effect of plasmin-derived fibrin(ogen) degradation products on alpha-thrombin cleavage of plasma Factor XIII was studied to identify the fibrin polymer structure that promotes Factor XIIIaExpand
