In enzymology, a protein-glutamine gamma-glutamyltransferase (EC 2.3.2.13) is an enzyme that catalyzes the chemical reaction

Contents

protein glutamine + alkylamine protein N5-alkylglutamine + NH3

Thus, 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.

Nomenclature

This enzyme belongs to the family of transferases, specifically the aminoacyltransferases. The systematic name of this enzyme class is protein-glutamine:amine gamma-glutamyltransferase. Other names in common use include:

Structural studies

As of late 2007, 19 structures have been solved for this class of enzymes, with PDB accession codes 1EVU, 1EX0, 1F13, 1FIE, 1G0D, 1GGT, 1GGU, 1GGY, 1IU4, 1KV3, 1L9M, 1L9N, 1NUD, 1NUF, 1NUG, 1QRK, 1RLE, 1SGX, and 1VJJ.
