A model for the reaction mechanism of the transglutaminase 3 enzyme

Ahvazi B, Steinert P

  • KMID: 1109310
  • Exp Mol Med.
  • 2003 Aug;35(4):228-242.
Transglutaminase enzymes (TGases) catalyze the calcium dependent formation of an isopeptide bond between protein-bound glutamine and lysine substrates. Previously we have shown that activated TGase 3 acquires two additional calcium...
