Enzyme Information

2.3.2.13
Protein-glutamine gamma-glutamyltransferase.
based on mapping to UniProt P00488
Protein glutamine + alkylamine = protein N(5)-alkylglutamine + 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 crosslinks.
