The effect of various phenols on the conversion of [4-14C]estradiol to water-soluble products by estrogen-induced uterine peroxidase (EC 1.11.1.7) has been investigated. Evidence was provided that those phenols which enhanced the oxidation of estradi

A peroxidase, purified from rat small intestine to apparent homogeneity as judged by polyacrylamide-gel electrophoresis, exhibited an absorbance ratio (A412/A280) of 0.783. Its Mr (44000 +/- 1000) and spectral properties were similar to those of the

1. The trans-epoxide of diethylstilboestrol and its pinacolone were synthesized chemically and the pinacolone shown to be formed from the epoxide by a non-enzymic process. 2. [14C]Diethylstiboestrol epoxide was converted by rat liver microsomal fract

The distribution of oestrogen-induced peroxidase in the resuspended 8000g pellet of rat uterine homogenates was examined by centrifugation in a sucrose density gradient. Within 10h of treatment with oestradiol, peroxidase activity was found in a regi

1. An enzyme that can be induced in rat uteri by oestrogens and that catalyses the oxidation of guaiacol and the metabolism and binding of [4-14C]oestradiol to protein in the presence of H2O2 was partially purified by (NH4)2SO4 fractionation and poly

Release of 3H2O from regiospecifically labeled estradiol was measured during 2-hydroxylation of this estrogen by rat liver microsomes. The amount of tritium remaining in the isolated catechol estrogen was also determined. Virtually all the tritium wa

SUMMARY Oestrone administered in the form of subcutaneous pellets produced marked changes in the metabolism of [14C]oestradiol by male rat liver microsomes. The high yield of both 2-hydroxyoestradiol and water-soluble metabolites was decreased to the

1. Oestradiol hydroxylase activity, as measured by the formation of water-soluble products, was significantly higher in the smooth endoplasmic reticulum of rat liver than in the rough membrane. 2. The isolated membrane fractions retained their activi

1. An enzyme that catalyses the metabolism and binding of [4-14C]oestradiol to protein and to other high-molecular-weight substances in the presence of H2O2 was shown to be absent from the uteri of immature rats and to be induced by physiological dos

Inhibition studies with compounds having structural features in common with the natural estrogens have shown that 2-hydroxyestrone and 2-hydroxyestradiol are potent inhibitors of the rat liver microsomal system, which converts estrone to water-solubl
