Estradiol activation of uterine reduced diphosphopyridine nucleotide oxidase.
Previous studies from this laboratory have shown that rat uterine homogenates contain a reduced pyridme nucleotide oxidase which is activated by ‘2,4-dichlorophenol and other phenolic substances (1, 2). Oophorectomy reduces the activity of this enzyme system to negligible levels but prompt restoration of the oxidative rate was observed upon the administration of small amounts of estradiol to th...
متن کاملPurification and properties of reduced diphosphopyridine nucleotide oxidase from Azotobacter.
Few studies on purified bacterial reduced diphosphopyridine nucleotide (DPNH) or cytochrome oxidases have been reported, although cytochrome reduction by DPNH’ in crude bacterial extracts has repeatedly been described (l-6). Dolin (7, 8) purified a flavoprotein DPNH oxidase and peroxidase from Streptococcus jaecalis, and Lenhoff and Kaplan (9) and Lenhoff et al. (10) described the characteristi...
متن کاملSuccinic and reduced diphosphopyridine nucleotide oxidase systems of Ascaris muscle.
Although Ascaris lumbricoides, an adult intestinal nematode of the pig, lives in a habitat in which the oxygen tension is extremely low, considerable amounts of oxygen are taken up if the parasite is exposed to an aerobic environment (1, 2). Experiments with intact worms, homogenates, and particulate preparations confirmed these observations and demonstrated that oxygen uptake is dependent mark...
متن کاملThe mechanism of triosephosphate dehydrogenase inactivation by reduced diphosphopyridine nucleotide.
We have shown in a previous communication (1) that the enzyme triosephosphate dehydrogenase is rapidly inactivated in the presence of reduced diphosphopyridine nucleotide at physiological concentrations, temperature, and pH. Good stoichiometry was shown for the amount of enzyme inactivation, DPNH-X1 formation, and disappearance of sulfhydryl groups. It was then of particular interest to determi...
