Table 5.

Maximum velocity; Vmax and Michaelis-Menten constant; Km for different concentrations of column purified ‘fraction-14’.

S.N. Fraction-14 (μg/mL) Vmax (μM/min.) Km (μM)
1 0 2.95 70
2 0.83 2.50 74
3 1.66 2.33 80
4 3.32 2.28 90
5 4.15 2.13 90

Note: The alpha glucosidase concentration was 0.02 units/mL. The substrate, PNPG concentration was 0.01, 0.02, 0.04, 0.08, 0.1, 0.2, 0.4 and 0.8 mM. The differences among the values are considered to be statistically significant at p < 0.05. PNPG: p-nitrophenyl-α-D-glucopyranoside.
