| Maltose (α, 1g – 4g) | 0.52 | 116 |
| Lactose (β, 1gal – 4g) | NDA | 102 |
| Trehalulose d. (α, 1g –1f) | 8.41 | 185 |
| Sucrose (α, 1g – 2f) | NDA | 159 |
| Turanose (α, 1g – 3f) | 7.72 | 187 |
| Maltulose (α, 1g – 4f) | 3.28 | 75 |

a
Specific activity: nmol pNPαG6P hydrolyzed min −1 mg protein −1.
b
Specific activity: nmol F6P formed min −1 mg protein −1.
c
NDA: no detectable activity: all values are average rates from three separate assays.
d
Sugars in bold face are sucrose isomers.
