“…Cytochrome P-450E, the major hydrocarbon hydroxylating isozyme from scup, is the apparent major hydrocarbon-inducible P-450 isozyme (Klotz et al, 1983;. The potential for this isozyme to catalyze microsomal E 2 2-hydroxylase activity was determined by assaying microsomes from BNF-treated scup, which had high levels of P-450E, and from control scup which had low amounts of P-450E.…”
