2,5,2',5'-Tetrachlorobiphenyl (TCB) is one of the major components of PCB preparation, Kanechlor 400, which caused a mass food poisoning called Yusho in Japan in 1968 (Kuratsune 1996) and has phenobarbital (PB)-type inducing ability of rat liver microsomal enzymes (Yoshimura et al. 1979). The main metabolic pathway of this PCB isomer is 3-hydroxylation of aromatic ring catalyzed by cytochrome P450 (P450). So far, two groups of P450 superfamily, namely CYP1A and CYP2B subfamily, have been known to be involved in the hydroxylation of PCBs in mammals (Koga and Yoshimura 1996). In particular, the 3-hydroxylation of 2,5,2',5'-TCB is catalyzed by some P450 isoforms belonging to CYP2B subfamily, for example, CYP2B1 and 2B2 in rat liver and P450HPB-1 in hamster liver (Ishida et al. 1990; Koga et al. 1995a).
