Enzymatic transfer and hydrolysis involving glutamine and asparagine.
The occurrence in bacteria of transferases, enzymes which catalyze the exchange of the p-aspartyl group of asparagine and the r-glutamyl group of glutamine with hydroxylamine or labeled ammonia, has been described (14). Transferase activities have also been found in extracts of mammalian tissues (5), in the mold Neurospora crassa,l and in extracts of green plants (6-8). Whereas transferase acti...
متن کاملFormation of stable anhydrides from CoA transferase and hydroxamic acids.
Acetohydroxamic acid reacts with the enzyme-CoA form of succinyl-CoA:3-ketoacid coenzyme A transferase to give an inactive product with a rate constant of 860 M-1 min-1 at pH 8.1, 25 degrees C. The reaction is reversible in the presence of coenzyme A and has an equilibrium constant of 0.040. The product is an anhydride that is an analog of the intermediate that has been postulated in the normal...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولEnzymatic synthesis of phenyl fatty hydroxamic acids from canola and palm oils.
Phenyl fatty hydroxamic acids (PFHAs) were synthesized from canola or palm oils and phenyl hydroxylamine (FHA) catalyzed by Lipozyme TL IM or RM IM. The reaction was carried out by shaking the reaction mixture at 120 rpm. The optimization was carried out by changing the reaction parameters, namely; temperature, organic solvent, amount and kind of enzyme, period of reaction and the mol ratio of ...
