Comparison of the surface area of the four SMCs revealed that Sg-SMC has the most compact structure, which may contribute to the enhanced thermostability of Sg-SMC. Regarding the hydrogen bond network in the active site of Sg-SMC, a basic amino acid, Arg278, is involved, whereas the corresponding residue in other SMCs (Ser or Asn) does not form hydrogen bonds with metal-coordinating water molecules. Hydrogen bond formation between Arg278 and a Mg2+ ion-coordinating water molecule may be responsible for the higher optimal pH o
