An RNA Processing Activity That Debranches RNA Lariats

Science, 1985
The excised introns of pre-messenger RNA's (pre-mRNA's) and intron-containing splicing intermediates are in a lariat configuration in which the 5′ end of the intron is covalently joined by a 2′,5′-phosphodiester bond to a specific adenosine residue near the 3′ end of the intron. A 2′,5′-phosphodiesterase activity in HeLa cell extracts has been detected

Chloroplast RNA processing and stability

Photosynthesis Research, 2004
Primary chloroplast transcripts are processed in a number of ways, including intron splicing, internal cleavage of polycistronic RNAs, and endonucleolytic or exonucleolytic cleavages at the transcript termini. All chloroplast RNAs are also subject to degradation, although a curious feature of many chloroplast mRNAs is their relative longevity.

RNA Processing

1994
Abstract Post-transcriptional events are increasingly recognized as important sites of regulation of gene expression in eukaryotic cells and so RNA processing has rapidly become an area of intense research activity. These two volumes give detailed practical guidance on all the major aspects of this subject.

RNA processing in prokaryotic cells

BioEssays, 1993
AbstractRNA processing in Escherichia coli and some of its phages is reviewed here, with primary emphasis on rRNA and tRNA processing. Three enzymes, RNase III, RNase E and RNase P are responsible for most of the primary endonucleolytic RNA processing events. The first two are proteins, while RNase P is a ribozyme.

Telomerase RNA biosynthesis and processing

Biochemistry (Moscow), 2012
Telomerase synthesizes repetitive G-rich sequences (telomeric repeats) at the ends of eukaryotic chromosomes. This mechanism maintains the integrity of the genome, as telomere shortening leads to degradation and fusion of chromosomes. The core components of telomerase are the telomerase catalytic subunit and telomerase RNA, which possesses a small ...

RNA processing in malarial parasites

Parasitology Today, 1993
RNA processing in malarial parasites is a relatively new focus o f scientific research. Although only a few transcripts have been characterized in depth, a few patterns are beginning to emerge. Alexandra Levitt here reviews post-transcriptional processing in Plasmodium.
