1 Cooperativity in CYP2E1 metabolism of acetaminophen and styrene mixtures. Acetaminophen cytochrome P450 family 2 subfamily E member 1 Homo sapiens
2 Herein, we demonstrated that in vitro CYP2E1 metabolic activation of acetaminophen and styrene mixtures could not be explained through the Michaelis-Menten mechanism or any models relying on that premise. Acetaminophen cytochrome P450 family 2 subfamily E member 1 Homo sapiens
3 In this case, acetaminophen competed with styrene for CYP2E1 (Ki=830muM and Ksi=180muM for catalytic and effector sites, respectively) and resulted in cooperative impacts on binding and catalysis. Acetaminophen cytochrome P450 family 2 subfamily E member 1 Homo sapiens
