Structure comparisons amongst related enzymes. The monomer structure and the front view, side view and top view of the overall structure are represented from the left to right for each enzyme. (a) A. globiformis D-allulose 3-epimerase (AgD-AE), (b) M. loti L-ribulose 3-epimerase (MlL-RE), (c) P. cichorii D-tagatose 3-epimerase (PcD-TE), (d) C. cellulolyticum D-psicose 3-epimerase (CcD-PE), (e) A. tumefaciens D-psicose 3-epimerase (AtD-PE). In (a) and (e) one dimer is shown as a ribbon model to show the position of α8 in the homotetramer. |
