Exoribonucleases and Endoribonucleases

EcoSal Plus, 2004
This review provides a description of the known Escherichia coli ribonucleases (RNases), focusing on their structures, catalytic properties, genes, physiological roles, and possible regulation. Currently, eight E. coli exoribonucleases are known.

5′-3′ Exoribonucleases

2011
The 5′-3′ exoribonucleases have important functions in RNA processing, RNA degradation, RNA interference, transcription, and other cellular processes. The Xrn1 and Xrn2/Rat1 family of enzymes are the best characterized 5′-3′ exoribonucleases, and there has been significant recent progress in the understanding of their structure and function. Especially,

Structures of 5′–3′ Exoribonucleases

The Enzymes, 2012
5'-3' Exoribonucleases (XRNs) have important functions in RNA processing, RNA turnover and decay, RNA interference, RNA polymerase transcription, and other cellular processes. Their sequences share two highly conserved regions, CR1 and CR2. The cytoplasmic Xrn1 and the nuclear Xrn2/Rat1 are found in yeast and animals, and XRNs are found in most other ...

Exoribonucleases and their multiple roles in RNA metabolism

Progress in Nucleic Acid Research and Molecular Biology, 2000
In recent years there has been a dramatic shift in our thinking about ribonucleases (RNases). Although they were once considered to be nonspecific, degradative enzymes, it is now clear that RNases play a central role in every aspect of cellular RNA metabolism, including decay of mRNA, conversion of RNA precursors to their mature forms, and end-turnover

Structure and Degradation Mechanisms of 3′ to 5′ Exoribonucleases

2011
Exoribonucleases are enzymes that cleave RNA molecules by removing terminal nucleotides from the 3′ or 5′ end of the RNA molecules. They are key factors in RNA metabolism and have a relevant role in the processing and degradation of all types of RNAs.

Chapter 5 The Role of 3′–5′ Exoribonucleases in RNA Degradation

Progress in Molecular Biology and Translational Science, 2009
RNA degradation is a major process controlling RNA levels and plays a central role in cell metabolism. From the labile messenger RNA to the more stable noncoding RNAs (mostly rRNA and tRNA, but also the expanding class of small regulatory RNAs) all molecules are eventually degraded.
