Abstract: Cytochrome P450(CYP450) is one of most important enzymes to metabolize endogenous and exogenous substrates in vivo.With the development of molecular biology and recombinant technology, the manipulating and heterogeneous expression of CYP450 cDNA become possible.Many kinds of heterogeneous expression systems have been generally operated nowadays, of which there are advantages and disadvantages respectively.It is usual to express mammalian CYP450s using E.coli as host in Lab, but different protein production and enzyme activity are brought by different expression systems and purification procedures.The present application of different expression modes using E.coli for mammalian CYP450 cDNA will be introduced as well as their advantages and the limits respectively.

Key words: heterogeneous expression, cytochrome P450, E.coli
