title: Newly biosynthesized cytochrome P-450 associated with the golgi apparatus from livers of rats induced with phenobarbital.
abstract: 1. Cytochrome P-450 has been detected in preparations of golgi apparatus from the livers of phenobarbital-induced rats. 2. Newly biosynthesized cytochrome P-450 is also present in preparations of golgi apparatus. By using three different techniques to fractionate the golgi into vesicle contents and membrane components it was found that newly biosynthesized cytochrome P-450 is associated solely with the membrane fraction. 3. By investigating the susceptibility of cytochrome P-450, present in the golgi apparatus, to the action of trypsin it was found that the majority was oriented on the cytosolic face of the membrane.
