Metabolism of various polyaromatic hydrocarbons by recombinant CYP2F2

Substrate	k_cat	K_m	Specificity Constant
	min⁻¹	μM	M⁻¹s⁻¹
Naphthalene^1-a	104	3	5.8 × 10⁵
2-Methylnaphthalene	67.6	3.7	3.05 × 10⁵
1-Nitronaphthalene	17.1	21.5	1.33 × 10⁴
Anthracene^1-b	0.14 ± 0.04
Benzo[a]pyrene^1-b	0.04 ± 0.00

↵1-a Activity for recombinant mouse CYP2F2 (Shultz et al., 1999).
↵1-b Activity is based on total metabolites formed and is expressed as the mean ± S.D. of three incubations performed using 100 μM substrate.
