additional information | activity is completely lost when the electron-transferring system is replaced by that of microsomes, i.e. NADPH-cytochrome P-450 reductase purified from rat liver microsomes. The omission of cytochrome P-450, adrenodoxin, or NADPH-adrenodoxin reductase results in complete loss of enzyme activity | Rattus norvegicus | |
