basic FUNCTION	hydroxylating coumarin, and also metabolizing nicotine, aflatoxin B1, nitrosamines, and some pharmaceuticals
	also catalyzing nicotine C-oxidation leading to cotinine formation, a major metabolic pathway of nicotine
	important hepatic Phase I enzyme that metabolizes approximately 3p100 of therapeutic drugs (Di 2009)
	plays a major role in the oxidation of nicotine in human liver microsomes (Thorgeirsson 2010)
