TreX is an oligomer, as it exists in a dimeric state and a tetrameric state, both of which exhibit different enzymatic activities. All subunits are identical, where the monomer contains a total of 612 amino acids <ref name="Woo" />. The polypeptide folds into two secondary structures, a β-sandwhich in the N terminal region, comprised of six β-strands and a (β/α)8 – barrel motif in the central domain, comprised of eight parallel α-strands which encircle eight parallel β-strands. The sequence composition of the TreX monomer exhibits a high degree of homology to the isoamylase debranching enzyme of Pseudomona, however the TreX monomer mainly deviates from this similarity in its substrate binding groove and the absence of a calcium ion ligand <ref name="Woo" />. | TreX is an oligomer, as it exists in a dimeric state and a tetrameric state, both of which exhibit different enzymatic activities.
