کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
15 صفحه اولDetermination of the Paracoccus denitrificans SOS box.
By gel retardation experiments with crude cell extracts of Paracoccus denitrificans it was demonstrated that a protein specifically binds to the promoter of the P. denitrificans recA gene. PCR mutagenesis of the recA promoter showed that the GAACN7GAAC motif is required for the formation of the DNA-protein complex. This protein also binds to the GTTCN7GTTC motif, which is present in the promote...
متن کاملThe terminal oxidases of Paracoccus denitrificans.
Three distinct types of terminal oxidases participate in the aerobic respiratory pathways of Paracoccus denitrificans. Two alternative genes encoding sub unit I of the aa3 -type cytochrome c oxidase have been isolated before, namely ctaDI and ctaDII. Each of these genes can be expressed separately to complement a double mutant (ActaDI, ActaDII), indicating that they are isoforms of subunit I of...
متن کاملThe nitric oxide reductase of Paracoccus denitrificans.
The nitric oxide (NO) reductase activity of the cytoplasmic membrane of Paracoccus denitrificans can be solubilized in dodecyl maltoside with good retention of activity. The solubilized enzyme lacks NADH-dependent activity, but can be assayed with isoascorbate plus 2,3,5,6-tetramethylphenylene-1,4-diamine as electron donor and with horse heart cytochrome c as mediator. Reduction of NO was measu...
متن کاملAutotrophic Growth of Paracoccus denitrificans in Aerobic Condition and the Accumulation of Biodegradable Plastics from CO2
The cell growth on H2 and O2 as the energy source and CO2 as the sole carbon source in the autotrophic culture condition was tested for the gram-negative bacteria Paracoccus spp. The aerobic growth in the autotrophic condition was only observed in Paracoccus denitrificans NBRC13301 and P.pantotrophus NBRC102493. Both strains were sensitive to O2 in particular the growth of P.pantotrophus was co...
