The Supplementary Information file that accompanies this article contains errors.

In the legend of Supplementary Figure S3 where:

“The structure of wild-type endo-levanase (dark blue) is superimposed on the structure of E221A mutant (light blue). Levantetraose (magenta) and water molecules are from the E221A structure. Fructose-binding subsites, catalytic amino acids, two alternate conformations of Gln239, and C2, O6, and C6 from β-2,6-linkage are designated.”
