The steroid 16α-hydroxylase system in mammalian liver

Steroids, 1966
Abstract The 16α-hydroxylation of testosterone and androst-4-ene-3, 17-dione (2) and of estradiol-17β (3) takes place in the presence of a microsomal fraction of rat liver. The rate of 16α-hydroxylation of 3β-hydroxyandrost-5-en-17-one (DHA) by liver slices is significantly higher for male than for female adult rats (4).

Steroid 11β-Hydroxylase Deficiency

2001
Inherited defects in cortisol biosynthesis are collectively termed congenital adrenal hyperplasia [reviewed in (1)]. Steroid 21-hydroxylase deficiency is, by far, the most common of these defects; it is reviewed elsewhere in this volume. This chapter reviews a related disease, steroid 11β-hydroxylase deficiency [reviewed in greater detail in (2)].

Heterogeneity of the Bovine Adrenal Steroid 21-Hydroxylase

Endocrine Research, 1989
The results presented indicate that purified cytochrome P-45021 which migrated upon SDS gel electrophoresis essentially as a single band, is further separable into different species by ion-exchange chromatography. The P-450 eluted from the CM-Sephadex column at different points along the buffer concentration gradient, exhibited significant differences ...
