Time course for the hydrolysis of β-CD by MAG1.

<p>The different product selectivity values were observed when different concentrations of the enzyme were used; (A) 0.4 U MAG1/mg β-CD and (B) 1.6 U MAG1/mg β-CD. Hydrolysis products consisted of M1, glucose; M2, maltose; M3, maltotriose; M4, maltotetraose; M5, maltopentaose; M6, maltohexaose; and M7, maltoheptaose. The product proportion was presented as a mean percentage from three triplicate experiments. The standard deviations were less than 0.6%.
