What You Need to Know
Microbial transglutaminase (MTGase) catalyzes acyl transfer reactions between γ-carboxamide groups of glutamine residues and ε-amino groups of lysine residues, forming ε-(γ-glutamyl)lysine isopeptide bonds.
Enables creation of uniform portions from cheaper cuts, reduces waste, and allows novel texture engineering.
