In enzymology a protein-glutamine gamma-glutamyltransferase (EC 2.3.2.13) is an enzyme that catalyzes the chemical reactionprotein glutamine + alkylamine protein N5-alkylglutamine + NH3Thus the two substrates of this enzyme are protein glutamine and alkylamine whereas its two products are protein N(5)-alkylglutamine and NH3.This enzyme participates in complement and coagulation cascades and Huntington’s disease. It employs one cofactor calcium.
