From: Selecting β-glucosidases to support cellulases in cellulose saccharification

  Activation energy, Ea(kJ mol-1)a Binding enthalpy, ΔH0(kJ mol-1)a
  k cat(h) kcat(h)/KM(h) K M(h) K i(Glc)
N188BG 47.6 ± 1.3 29.5 ± 1.7 18.1 ± 1.0 19.6
TaBG3 39.8 ± 1.9 26.2 ± 2.3 13.6 ± 1.2 22.8
AtBG3 48.2 ± 2.7 20.5 ± 2.4 27.7 ± 3.3 24.6
  1. aFor the parameter p, the activation energy (for kcat(h) and kcat(h)/KM(h)) and standard binding enthalpy (for KM(h) and Ki(Glc)) was obtained from the slope of the line in the coordinates of ln(p) versus 1/T. For the data, see Additional file 1: Figure S1.
