| 1.1.5.2 | additional information | absolute specificity with respect to the C1 position, only sugars are oxidized which have the same configuration of the H/OH substituents at this site as the beta-anomer of glucose. Absolute specificity with respect to the overall conformation of the sugar molecule, sugars with a 4C1 chair conformation are substrates, those with a 1C4 one are not. The nature and configuration of the substituents at the 3-position are hardly relevant for activity, and an equatorial pyranose group at the 4-position exhibits only a specific hindering of the binding of the aldose moiety of a disaccharide | Acinetobacter calcoaceticus | ? | - |

| 1.1.99.35 | additional information | kinetic mechanism of sGDH consists of (a) step(s) in which a fluorescing intermediate is formed, and a subsequent, irreversible step, determining the overall rate of the reductive half-reaction. The pH optimum determined for glucose oxidation appears to be 7.0, implying that reoxidation of sGDHred is rate-limiting with those electron acceptors displaying a different value under steady-state conditions. | Acinetobacter calcoaceticus | ? | - |
