Substrate specificity of WT and Y172A CgAMs in disproportionation reaction using malto-oligosaccharide (maltose [G2] to maltoheptaose [G7]) as the substrate. Data are shown as the mean ± SD and are derived from 3 independent experiments. *, P < 0.05 (Student's t test) with respect to the disproportionation reaction of WT CgAM.
