Dual targeting of aminoacyl-tRNA synthetases to the mitochondrion and complex plastid in chlorarachniophytes.
In plants, many nucleus-encoded proteins are targeted to both mitochondria and plastids, and this process is generally mediated by ambiguous N-terminal targeting sequences that are recognized by receptors on both organelles. In many algae, however, plastids were acquired by secondarily engulfing green or red algae, which were retained within the endomembrane system. Protein targeting to these s...
متن کاملIn vitro import of a nuclearly encoded tRNA into the mitochondrion of Trypanosoma brucei.
All of the mitochondrial tRNAs of Trypanosoma brucei have been shown to be encoded in the nucleus and must be imported into the mitochondrion. The import of nuclearly encoded tRNAs into the mitochondrion has been demonstrated in a variety of organisms and is essential for proper function in the mitochondrion. An in vitro import assay has been developed to study the pathway of tRNA import in T. ...
متن کاملCoordination of tRNA nuclear export with processing of tRNA.
Eukaryotic tRNAs are synthesized in the nucleus and need to be exported to the cytoplasm where they function in translation. tRNA export is mediated by exportin-t, which binds tRNA directly and with high affinity. tRNAs are initially synthesized as precursor molecules. Maturation to functional tRNA takes place in the nucleus, precedes export, and includes trimming of the 5' and 3' ends, posttra...
متن کاملthe comparative impact of prompts and recasts in processing instruction versus meaningful output-based instruction on efl learners’ writing accuracy
the purpose of the present study was to see which one of the two instruction-processing instruction (pi) and meaningful output based instruction (mobi) accompanied with prompt and recast- is more effective on efl learners’ writing accuracy. in order to homogenize the participants in term of language proficiency a preliminary english test (pet) was administrated between 74 intermediate students ...
Lead and the mitochondrion.
In studies on the distribution of lead in rats given drinking water containing lead acetate at concentrations: 0, 100, 500, 1000 and 5000 ,ugPb/l for one year, no change was observed in the organ distribution of lead, or in the subcellular distribution of lead in the organelles in the heart. The mitochondrial enzyme, ferrochelatase, was significantly depressed in both the 500 and 1000 ptg/l gro...
