Description
Transglutaminase catalyzes covalent cross‑linking of meat proteins, creating firm gels.
Technical
The zinc‑dependent amidotransferase forms γ‑glutamyl‑ε‑lysine isopeptide bonds between glutamine and lysine residues, requiring a catalytic triad (Cys‑His‑Glu). Optimal activity occurs at pH 6.0–7.5 and 37–45 °C, and the reaction is sensitive to temperature, pH, enzyme dosage, and reaction time.
