  1. aOne unit of enzyme activity corresponds to 1 μmol of glucose released in 1 min. Measurements were conducted in triplicate for each enzyme at 35 °C, using a buffer solution consisting of 50 mM Na2HPO2–KH2PO4 at pH 6.0. The reported values represent the means accompanied by their respective standard deviations
  2. bThe specific activity of CBM6E WT is from the reference [19]
