Characterization of 6 alpha-hydroxylation of taurochenodeoxycholic acid in pig liver.

The properties of the species-specific 6 alpha-hydroxylation of taurochenodeoxycholic acid were studied in subcellular fractions from pig liver. The hydroxylation was observed in microsomes but not in mitochondria. A partially purified cytochrome P-450 fraction in the presence of NADPH-cytochrome P-...

The hydroxylation was observed in microsomes but not in mitochondria. A partially purified cytochrome P-450 fraction in the presence of NADPH-cytochrome P-450 reductase, NADPH, and phospholipid catalyzed 6 alpha-hydroxylation of taurochenodeoxycholic acid at a 160-fold higher rate than the microsomes. This cytochrome P-450 fraction did not catalyze 6 alpha-hydroxylation of 5 beta-cholestane-3 alpha,7 alpha-diol or testosterone, nor did it catalyze 7 alpha-hydroxylation of cholesterol.http://www.sciencedirect.com/science/article/pii/S0022227520387848
