   3.2.1.B26 | 4-nitrophenyl-beta-D-galactopyranoside |
at low and intermediate temperatures (from 25°C to 50°C), the enzyme displays an inhibition by excess substrate and at high temperature (70 and 80°C) an activation, for 4-nitrophenyl-beta-D-galactopyranoside as substrate |
724406 |
| 3.2.1.B26 | acetonitrile |
maximal increase in enzyme activity at solvent concentrations of 15% (v/v) with 4-nitrophenyl beta-D-fucopyranoside as substrate |
724154 |
| 3.2.1.B26 | butan-2-one |
maximum increase in enzyme activity (1.5fold compared to activity in buffer) is measured at 5% (v/v) solvent concentrations with 4-nitrophenyl beta-D-fucopyranoside as substrate |
724154 |
| 3.2.1.B26 | butanol |
the liberation of aglycone from aryl beta-D-glucosides is stimulated by alcohols in a manner suggesting specific interaction between alcohol and enzyme |
721315 |

| 3.2.1.B26 | methyl acetate |
5% (v/v), increases activity with 2-nitrophenyl beta-D-galactopyranoside, 4-nitrophenyl beta-D-fucopyranoside or 4-nitrophenyl beta-D-glucopyranoside |
724154 |
| 3.2.1.B26 | methyl acetate |

| 3.2.1.B26 | more |
this enzyme appears to be activated by pressure between atmospheric pressure and 2.5 kbar with a maximal activity at 1.25 kbar. However, this enzyme still displayed the best catalytic efficiency at atmospheric pressure because of a Km value drastically increased by pressure |
