Potent inhibition of human liver aldehyde oxidase by raloxifene.
The selective estrogen receptor modulator, raloxifene, has been demonstrated as a potent uncompetitive inhibitor of human liver aldehyde oxidase-catalyzed oxidation of phthalazine, vanillin, and nicotine-Delta1'(5')-iminium ion, with K(i) values of 0.87 to 1.4 nM. Inhibition was not time-dependent. Raloxifene has also been shown to be a noncompetitive inhibitor of an aldehyde oxidase-catalyzed ...
متن کاملTHE REDUCTION OF CYTOCHROME c BY XANTHINE OXIDASE
A number of substances such as oxygen, dyes, and nitrate can act as hydrogen acceptors for xanthine oxidase (1). It has now been found that cytochrome c is also reduced by this system. Since only one other enzyme has been isolated which reduces cytochrome c (2), it was of interest to study the reaction, particularly since Ball (3) has indicated that xanthine oxidase is a flavoprotein. The activ...
متن کاملThe reduction of cytochrome c by milk xanthine oxidase.
The reduction of cytochrome c by xanthine oxidase and the competitive inhibition of this process by carbonic anhydrase and by myoglobin have been studied by kinetic and by equilibrium binding methods. Carbonic anhydrases isolated from bovine and from human erythrocytes differed strikingly in their ability to inhibit competitively the reduction of cytochrome c. The KS for cytochrome c was a func...

متن کاملBiosynthesis of cytochrome c oxidase by isolated rat liver mitochondria.
When isolated mitochondria which have been labeled with [3H]leucine are solubilized and treated with anti-serum specific for cytochrome c oxidase, labeled polypeptides which correspond to the three largest polypeptides of this enzyme are immunoprecipitated. This indicates that the three largest polypeptides of cytochrome c oxidase which have Mr of 66,000, 39,000, and 23,000 are synthesized by i...
