Abstract

Synonym(s): Protein-glutamine gamma-glutamyltransferase, Fibrinoligase, TGase

Transglutaminases catalyse the post-translational modification of proteins at glutamine residues, with formation of isopeptide bonds. Members of the transglutaminase family usually have three domains: N-terminal , middle and C-terminal. The middle domain is usually well conserved, but family members can display major differences in their N- and C-terminal domains, although their overall structure is conserved [PubMed10411627]. This entry represents the C-terminal domain found in transglutaminases, which consists of an immunoglobulin-like beta-sandwich consisting of seven strands in two sheets with a Greek key topology.

The best known transglutaminase is blood coagulation factor XIII, a plasma tetrameric protein composed of two catalytic A subunits and two non-catalytic B subunits. Factor XIII is responsible for cross-linking fibrin chains, thus stabilizing the fibrin clot. Protein-glutamine gamma-glutamyltransferases are calcium-dependent enzymes that catalyse the cross-linking of proteins by promoting the formation of isopeptide bonds between the gamma-carboxyl group of a glutamine in one polypeptide chain and the epsilon-amino group of a lysine in a second polypeptide chain. TGases also catalyse the conjugation of polyamines to proteins [PubMed1683845, PubMed1974250].

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 8 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a Transglutaminase, two C-terminal domains domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 8 hidden Markov models representing the Transglutaminase, two C-terminal domains superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
