The MTG molecule forms a single, compact domain belonging to the alpha+beta folding class, containing 11 alpha-helices and 8 beta-strands. The alpha-helices and the beta-strands are concentrated mainly at the amino and carboxyl ends of the polypeptide, respectively. These secondary structures are arranged so that a beta-sheet is surrounded by alpha-helices, which are clustered into three regions [1].

protein-glutamine gamma-glutamyltransferase (bacterial)  M-CSA #761

Transglutaminases, TGase, catalyse an acyl transfer reaction in which gamma-caboxyamide groups of the peptide-bound glutamine residues act as acyl donors with e-amino lysine groups as acyl acceptors. The microbial tranglutaminase, MTG, from Streptoverticllium mobaraense is Ca2+ independent unlike mammalian TGases and folds in to aplate-like shape with a deep cleft at the edge of the molecule. MTG is secreted from the cytoplasm and is activated by proteolytic processing. The additional pro-sequence consisting of 45 amino acid residues at the N terminus is cleaved off, resulting in the active form, the mature enzyme. Industrial applications of MTG include improving the physical and textural properties of protein-rich foods.
