additional information
isofornm CYP3A4 is the only enzyme tested which is active towards bile acids taurochenodeoxycholate and lithocholate. The enzyme catalyzes an efficient 6alpha-hydroxylation of both taurochenodeoxycholic acid and lithocholic acid

Organism
physiological function
a strong correlation exists between 6alpha-hydroxylation of taurochenodeoxycholic acid, CYP3A levels and testosterone 6beta-hydroxylation. There is also a strong correlation between 6alpha-hydroxylation of lithocholic acid, CYP3A levels and testosterone 6beta-hydroxylation
