Enzyme	K_m (mg/mL)	k_cat (s^–1)	k_cat/K_m (s^–1 mg^–1 mL)
EcOpgD	8.6 ± 1.1 (0.44 ± 0.056)^b	29 ± 2	3.4 ± 0.2
CpSGL^a (GH144)	0.71 ± 0.15 (0.068 ± 0.014)^b	49 ± 4	69 ± 10
TfSGL^a (GH162)	0.18 ± 0.02 (0.015 ± 0.001)^b	31 ± 1	170 ± 10
EcOpgG		(0.11)^c

^aThe values of CpSGL and TfSGL are cited from Abe et al.²⁹ and Tanaka et al.³⁰, respectively.

^bThe values calculated using molar concentrations (mM) are shown in parentheses.

^cReaction velocity in the presence of 8 mg/mL β-1,2-glucan at pH 5.5 is shown in parenthesis.
