Specific P450 Content:
      300 pmol/mg protein

Cytochrome c Reductase Activity:
      600 nmol/min/mg protein

Typical P450 Activity Data (1)

Activity: Diclofenac 4'-hydroxylase

Linear with time up to: 60 min

Linear with P450 up to:
       150 pmol/ml

Vmax: 0.25 pmol/min/pmol CYP

Km: 60 µM

Typical P450 Activity Data (2)

Activity: Tolbutamide 4-hydroxylase

Linear with time up to: 60 min

Linear with P450 up to:
       100 pmol/ml

Vmax: 2 pmol/min/pmol CYP

Km: 1700 µM (see note below)

Note:The kinetic parameters given above were determined using tolbutamide concentrations from 40 - 500 µM, as the limit of solubility is reported to be around 740 µM. The margin of error is therefore likely to be high. The tolbutamide 4-hydroxylase activity of CYP2C41LR Bactosomes at 500 µM tolbutamide is approximately 0.5 pmol/min/pmol CYP.
