Human Mitochondrial Transcription Termination Exhibits
Human mitochondrial 16 S rRNA 3'-end formation requires a tridecamer template sequence and a trans-acting protein of -34 kDa. This protein binds tightly to its target sequence and further analysis of the protein-DNA complex revealed that the DNA is bent. Either T3, T7, Escherichia coli, or yeast mitochondrial RNA polymerase produced transcripts mapping at this termination site. With these heter...
متن کاملDynamic Regulation of Chloroplast Transcription’
Plastids are ubiquitous DNA-containing organelles present in plant cells. These organelles carry out numerous metabolic functions including photosynthesis, starch synthesis, and steps in lipid, terpenoid, amino acid, tetrapyrrole, and plant hormone biosynthesis. Some of these functions are highly expressed in differentiated plastids. For example, chloroplasts are specialized for photosynthesis,...
متن کاملTransients in chloroplast gene transcription.
Transcriptional regulation of chloroplast genes is demonstrated by Quantitative Polymerase Chain Reaction (qPCR). These genes encode apoproteins of the reaction centres of photosystem I and photosystem II. Their transcription is regulated by changes in wavelength of light selectively absorbed by photosystem I and photosystem II, and therefore by the redox state of an electron carrier located be...
متن کاملFactor-dependent archaeal transcription termination.
RNA polymerase activity is regulated by nascent RNA sequences, DNA template sequences, and conserved transcription factors. Transcription factors promoting initiation and elongation have been characterized in each domain, but transcription termination factors have been identified only in bacteria and eukarya. Here we describe euryarchaeal termination activity (Eta), the first archaeal terminati...
متن کاملThe yeast RPL9B gene is regulated by modulation between two modes of transcription termination.
RNA Pol II transcription termination can occur by at least two alternative pathways. Cleavage and polyadenylation by the CPF/CF complex precedes mRNA transcription termination, while the Nrd1 complex is involved in transcription termination of non-coding RNAs such as sno/snRNAs or cryptic unstable transcripts. Here we show that transcription of RPL9B, one of the two genes coding for the ribosom...
