A shared RNA-binding site in the Pet54 protein is required for translational activation and group I intron splicing in yeast mitochondria
The Pet54p protein is an archetypical example of a dual functioning ('moonlighting') protein: it is required for translational activation of the COX3 mRNA and splicing of the aI5beta group I intron in the COX1 pre-mRNA in Saccharomyces cerevisiae mitochondria (mt). Genetic and biochemical analyses in yeast are consistent with Pet54p forming a complex with other translational activators that, in...
متن کاملsynthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Synthesis and processing of ribosomal RNA in isolated yeast mitochondria.
The synthesis and processing of the 15S and 21S rRNAs have been studied in isolated yeast mitochondria. When mitochondrial transcripts were labeled with [alpha-32p]UTP in an incubation mixture containing 50 microM ATP, the transcripts from the genes for the large and small ribosomal RNAs accumulated in the form of putative precursor molecules. The labeled pre-21S rRNA was converted to mature 21...
متن کاملLipoic acid synthesis and attachment in yeast mitochondria.
Lipoic acid is a sulfur-containing cofactor required for the function of several multienzyme complexes involved in the oxidative decarboxylation of alpha-keto acids and glycine. Mechanistic details of lipoic acid metabolism are unclear in eukaryotes, despite two well defined pathways for synthesis and covalent attachment of lipoic acid in prokaryotes. We report here the involvement of four gene...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
