UGT Isoform | Km (μM) | Vmax (nmol/min/mg protein) | CLint (Vmax/Km) (μl/min/mg protein) |
UGT1A3 | 78.4 | 1.33 | 17.0 |

The best fit of data was determined by the examination of required parameters using SigmaPlot 8.0. The formation of 20-HETE glucuronide showed a fit to Michaelis-Menten kinetics. Details are described in the Experimental Procedures.
