Protein Domain : IPR002931

Name  Transglutaminase-like Short Name  Transglutaminase-like
Type  Domain Description  This domain is found in many proteins known to have transglutaminase activity, i.e. which cross-link proteins through an acyl-transfer reaction between the gamma-carboxamide group of peptide-bound glutamine and the epsilon-amino group of peptide-bound lysine, resulting in a epsilon-(gamma-glutamyl)lysine isopeptide bond. Tranglutaminases have been found in a diverse range of species, from bacteria through to mammals. The enzymes require calcium binding and their activity leads to post-translational modification of proteins through acyl-transfer reactions, involving peptidyl glutamine residues as acyl donors and a variety of primary amines as acyl acceptors, with the generation of proteinase resistant isopeptide bonds []. Sequence conservation in this superfamily primarily involves three motifs that centre around conserved cysteine, histidine, and aspartate residues that form the catalytic triad in the structurally characterised transglutaminase, the human blood clotting factor XIIIa' []. On the basis of the experimentally demonstrated activity of the Methanobacterium phage psiM2pseudomurein endoisopeptidase [], it is proposed that many, if not all, microbial homologues of the transglutaminases are proteases and that the eukaryotic transglutaminases have evolved from an ancestral protease [].A subunit of plasma Factor XIII revealed that each Factor XIIIA subunit is composed of four domains (termed N-terminal beta-sandwich, core domain (containing the catalytic and the regulatory sites), and C-terminal beta-barrels 1 and 2) and that two monomers assemble into the native dimer through the surfaces in domains 1 and 2, in opposite orientation. This organisation in four domains is highly conserved during evolution among transglutaminase isoforms [].
