Fig. 1From: Characterization of cold-active trehalose synthase from Pseudarthrobacter sp. for trehalose bioproductionOverall predicted three-dimensionals structure of PaTreS. A Cartoon representation of four distinct domains of ArTreS including domain A, B, C, and subdomain S7 represented in pink, yellow, green, and blue, respectively. B The superimposition of PaTreS and TtTS from Thermobaculum terrenum (PDB 5 × 7u) represents the proposed catalytic residues (H128/D225/E267/H334/D335) and Mg2+ ionsBack to article page
