WebFeb 5, 2024 · Cytochrome P450 2A6 (CYP2A6) is an important member of the CYP450 family. However, most studies on CYP2A6 so far have focused on nicotine metabolism [ 5 ]. Several studies hint at a previously unappreciated aspect of CYP2A6 in tumor [ 6 , 7 , 8 ], but current understanding of CYP2A6 function in tumor is controversial. WebAbstract. Mycobacteria share a common cholesterol degradation pathway initiated by oxidation of the alkyl side chain by enzymes of cytochrome P450 (CYP) families 125 and 142.
