Abstract:
:Using baculovirus a cDNA for cytochrome P450 (P450F1) belonging to rabbit P450IIB subfamily was expressed in Spodoptera frugiperda cells, where P450F1 was located on electron-dense structures (derived from the endoplasmic reticulum) present in both the cytoplasm and nucleus. Partially purified P450F1 exhibited absorption spectra similar to those of P450(1), the major phenobarbital-inducible form in rabbit liver. Like P450(1), P450F1 could oxidize aminopyrine, benzphetamine, 7-ethoxycoumarin, 1-nitropropane, and 2-nitropropane, though its activities toward benzphetamine and 7-ethoxycoumarin were about 50 and 5%, respectively, of those of P450(1). It is concluded that the members of P450IIB subfamily can act on a variety of xenobiotics, although substrate preferences are different among them.
