Fig. 1From: Constructing xenobiotic maps of metabolism to predict enzymes catalyzing metabolites capable of binding to DNARepresentation of Heterocyclic Aromatic Amine Metabolism. This metabolism is divided into two steps: Phase I (in green) is known as “oxidation reaction” and catalyzed by cytochromes P450 (CYPs) and Phase II (in red) is known as a “conjugation reaction”, catalyzed by UDP-glucuronyltransferases (UGTs), N-actetyltransferases (NATs), Sulfotransferases (SULTs) or Glutathione S-transferase (GSTs)Back to article page
