1 An antibody directed against the male-specific cytochrome P-450 UT-A decreased androst-4-ene-3,17-dione 16 alpha-hydroxylase activity to 13% of control in hepatic microsomes from untreated rats. 4-androstene cytochrome P450, subfamily 2, polypeptide 11 Rattus norvegicus
2 An antibody directed against the male-specific cytochrome P-450 UT-A decreased androst-4-ene-3,17-dione 16 alpha-hydroxylase activity to 13% of control in hepatic microsomes from untreated rats. 3,17-dione cytochrome P450, subfamily 2, polypeptide 11 Rattus norvegicus
3 Further, the increased susceptibility of androst-4-ene-3,17-dione 16 alpha-hydroxylase activity to inhibition by an antibody to cytochrome P-450 UT-A, following ferricyanide treatment of microsomes, suggests that this male sexually differentiated enzyme is also complexed after in vivo SKF 525-A dosage. Androstenedione cytochrome P450, subfamily 2, polypeptide 11 Rattus norvegicus
4 Further, the increased susceptibility of androst-4-ene-3,17-dione 16 alpha-hydroxylase activity to inhibition by an antibody to cytochrome P-450 UT-A, following ferricyanide treatment of microsomes, suggests that this male sexually differentiated enzyme is also complexed after in vivo SKF 525-A dosage. hexacyanoferrate III cytochrome P450, subfamily 2, polypeptide 11 Rattus norvegicus
5 Further, the increased susceptibility of androst-4-ene-3,17-dione 16 alpha-hydroxylase activity to inhibition by an antibody to cytochrome P-450 UT-A, following ferricyanide treatment of microsomes, suggests that this male sexually differentiated enzyme is also complexed after in vivo SKF 525-A dosage. Proadifen cytochrome P450, subfamily 2, polypeptide 11 Rattus norvegicus
