title: Protein engineering in studies on metabolism of toxic substances.
abstract: Expression of cytochrome P-450s, drug metabolizing enzymes, from their coding sequences in heterologous cells were developed and the enzymatically active P-450s were synthesized. cDNAs of various chimera or mutant P-450s were constructed and expressed. Thus, regions or residues important for the function of cytochrome P-450 were analyzed.
