The reaction of bromopyruvate with pyruvate kinase was demonstrated both by noting loss of catalytic activity with time and by incorporation of [14C]pyruvate. The first order rate constant for loss of catalytic activity when plotted as a function of bromopyruvate concentration fit a regular hyperbolic saturation function indicative of the formation of a complex with Ki = 15 mM prior to the inac...
mnco2o4 (mno-co2o3) nanocomposite as a binary oxide has been successfully prepared by precipitation method using cobalt nitrate and manganese nitrate as the precursors and then characterized by scanning electron microscopy-energy dispersive micro-analysis (sem-edx) and x-ray diffraction (xrd) techniques. in this work, we report the hydrolysis kinetics reactions of semi mustard (chloroethyl ethy...
Women with metabolic disorders, including obesity and diabetes, have an increased risk of developing endometrial cancer. However, the metabolism of endometrial tumors themselves has been largely understudied. Comparing human endometrial tumors and cells with their nonmalignant counterparts, we found that upregulation of the glucose transporter GLUT6 was more closely associated with the cancer p...
Pyruvate:ferredoxin oxidoreductase and the pyruvate dehydrogenase multi-enzyme complex both catalyse the CoA-dependent oxidative decarboxylation of pyruvate but differ in size, subunit composition and mechanism. Comparison of the pyruvate:ferredoxin oxidoreductase from the protozoon Trichomonas vaginalis and the pyruvate dehydrogenase component of the Escherichia coli pyruvate dehydrogenase com...
حفاظت از گروههای عاملی از مراحل اجتناب ناپذیر در سنتز آلی است، در این بین محافظت از گروههای آمینی بسیار حائز اهمیت است. روشهای متعددی از قبیل فرمیله کردن، استیله کردن، محافظت بصورت boc و موارد زیاد دیگری جهت محافظت از گروههای آمینی تاکنون گزارش شده است. از طرف دیگر توسعه و کاربرد کاتالیست ها و حلالهای دوستدار محیط زیست و مزایای واکنشهای بدون حلال همچون سرعت بالای واکنش، خالص سازی آسان، کاهش آلو...
We investigated the possible sources of intracellular ATP which was previously shown essential for maintaining the muscarinic cationic channel activities (or currents; I(cat)) in guinea-pig ileal myocytes, using two variants of patch clamp techniques. Deprivation of external glucose or its replacement with 2-deoxyglucose significantly reduced the magnitude of I(cat), recorded with nystatin-perf...
One drug may suppress the effects of another. Although knowledge of drug suppression is vital to avoid efficacy-reducing drug interactions or discover countermeasures for chemical toxins, drug-drug suppression relationships have not been systematically mapped. Here, we analyze the growth response of Saccharomyces cerevisiae to anti-fungal compound ("drug") pairs. Among 440 ordered drug pairs, w...
