Transglutaminase from Microbial, Recombinant
Cat No.
NATE-3650
Description
Transglutaminases are a family of enzymes that catalyze the posttranslational modification of proteins by inserting an isopeptide bond within or between polypeptide chains. These enzymes catalyze the acyl transfer reaction between the γ-carboxyamide groups of peptidebound glutamine residues and a variety of primary amines, particularly the ε-amino group of lysine. The resulting crosslink is of great significance, since it is highly stable and also resistant to mechanical and proteolytic degradation.
