Enzyme Information

2.3.2.13

Protein-glutamine gamma-glutamyltransferase.

based on mapping to UniProt P21980

A protein-L-glutamine + a protein-L-lysine = a protein with an N(6)- (gamma-glutamyl)-L-lysine cross-link + NH(3).

-!- The gamma-carboxymide groups of peptide-bound glutamine residues act as acyl donors, and the 6-amino-groups of protein- and peptide-bound lysine residues act as acceptors, to give intra- and inter-molecular N(6)-(5-glutamyl)lysine cross-links.
