Alfentanil 29-39 mitochondrially encoded cytochrome b Homo sapiens 199-211 15557344-8 2005 Cytochrome b(5) qualitatively and quantitatively altered alfentanil metabolism, with b(5) coexpression having a greater effect than exogenous addition. Alfentanil 57-67 mitochondrially encoded cytochrome b Homo sapiens 0-12
