Application
This product from Sigma has been used to demonstrate that tissue transglutaminase (tTG) selectively deamidates gluten peptides, which results in strongly enhanced T cell-stimulatory activity.[1] It has also been used to assess immune responses to A-gliadin peptides.[2] Furthermore, it has been used to demonstrate that tTG selectively modifies gliadin peptides that are recognized by gut-derived T cells in celiac disease.[3]
Transglutaminase has been used in a study to improve quantifiable assays to fully characterize the role of transglutaminase in diseases such as Huntington′s disease and Alzheimer′s disease.Transglutaminase has also been used in a study to develop a nonradioactive dot blot assay for transglutaminase activity.
Biochem/physiol Actions
Transglutaminase from guinea pig liver consists of a single polypeptide chain of 691 amino acid residues. It has six potential glycosylation sites (Asn-X-Ser or Asn-X-Thr), but it is not glycosylated. The molecular mass is approximately 76.6 kDa.[4] It is calcium dependent and has several calcium binding sites. The enzyme is inhibited by iodoacetamide and N-ethylmaleimide in the presence of calcium.[5] It catalyzes the incorporation of small molecular weight amines into γ-glutamine sites of proteins. In the absence of small molecular weight amines, it catalyzes the cross linking of proteins that results in the formation of γ-glutamyl-ε-lysine side chain peptides. Liver transglutaminase is a nonzymogenic enzyme.[6]
Physical form
Lyophilized powder containing Tris and dithioerythritol
Other Notes
One unit will catalyze the formation of 1.0 μmole of hydroxamate per min from Nα-Z-Gln-Gly and hydroxylamine at pH 6.0 at 37 °C. (L-Glutamic acid γ-monohydroxamate is the standard.)

This paper is intended as a background to the topic of transglutaminases, while focusing on current ideas regarding the biological roles of these enzymes. Specifically, the following topics are discussed: geometry of forming gamma-glutamyl-epsilon-lysine cross-linked structures; energetic considerations; the gamma-glutamyl-epsilon-lysine
