the enzymes investigated were two phenobarbital-inducible cytochrome p-450 ( cyt . p-450 ) isoenzymes ( pb1 and pb2 , mol . wt . 52 000 and 53 500 , respectively ) , two 3-methylcholanthrene-inducible forms ( mc1 and mc2 , mol . wt . 54 500 and 57 000 , respectively ) , nadph-cytochrome p-450 reductase , the cytosolic glutathione transferases ( gsts ) b and c and the microsomal epoxide hydrolase with broad substrate specificity ( mehb ) .
