Activity of recombinant CYP9K1 against model substrates and insecticides

Substrate	Specific activity/depletion of parental compound, %
	−NADPH	+NADPH
7-Ethocycoumarin	No activity	10.6 ± 1.1
Deltamethrin	No depletion	32.0 ± 3.24
Bendiocarb	No depletion	No depletion
Pyriproxyfen	No depletion	38.0 ± 1.3

Activities are given in picomoles of 7-hydroxycoumarin per minute per picomole of P450 for the substrate 7-ethocycoumarin and as percentage depletion of the parental insecticides under assay conditions.
