(a) Overall structure of the M. loti L-RE monomer (stereoview). α-Helices (numbered from α1 to α8) and β-strands (numbered from β1 to β8) are indicated in red and yellow, respectively; Mn2+, purple. (b) Structural comparison of M. loti L-RE and other ketose 3-epimerases (stereoview). M. loti L-RE structure (red) superimposed on those of P. cichorii D-TE (cyan), A. tumefaciens D-PE (green) and C. cellulolyticum D-PE (yellow). |
