Mixing speed (rpm) | Temp (°C) | Apparent Vmax (mU/mg) | Apparent Km (mM) |
---|---|---|---|
1,000 | 30 | 170 ± 90 | 0.21 ± 0.99 |
1,400 | 30 | 140 ± 15 | 0.30 ± 0.26 |
1,400 | 22 | 160 ± 90 | 0.121 ± 1.0 |
2,200 | 22 | 390 ± 70 | 0.56 ± 0.54 |
2,200b | 22 | 340 ± 40 | 0.078 ± 2.2 |
Vmax and Km were determined from Michaelis-Menten fits of initial rate data points that were determined at three different apparent substrate concentrations (2 mM, 4 mM, and 8 mM), each in at least two independent experiments.
Data points obtained in a single experiment in the presence of 2.5% isopropyl alcohol.
