Ribonucleases (RNases) are mediators in most reactions of RNA metabolism. In recent
years, there has been a surge of new information about RNases and the roles they play in …

RNase E is an essential endonuclease that is abundant in many bacteria and plays an
important part in all aspects of RNA metabolism. It functions as part of a large …

The continuous degradation and synthesis of prokaryotic mRNAs not only give rise to the
metabolic changes that are required as cells grow and divide but also rapid adaptation to …

The study of the biosynthetic pathway leading to synthesis of the amino acid histidine in
prokaryotes and lower eukaryotes was begun more than 40 years ago (119) and has …

Nuclear ribonuclease (RNase) P is a ubiquitous essential ribonucleoprotein complex, one of
only two known RNA-based enzymes found in all three domains of life. The RNA component …

Ribonuclease P (RNase P) is a ribonucleoprotein enzyme that cleaves precursor tRNA
transcripts to give mature 5′ ends. RNase P in eubacteria has a large, catalytic RNA …

Abstract Ribonuclease P (RNase P) is a ubiquitous endonuclease that catalyses the
maturation of the 5′ end of transfer RNA (tRNA). Although it carries out a biochemically …

▪ Abstract The stability of mRNA in prokaryotes depends on multiple factors and it has not yet
been possible to describe the process of mRNA degradation in terms of a unique pathway …

The instability of messenger RNA is fundamental to the control of gene expression. In
bacteria, mRNA degradation generally follows an “all-or-none” pattern. This implies that if …

ABSTRACT Ribonuclease P (RNase P) is an ancient and essential endonuclease that
catalyses the cleavage of the 5′ leader sequence from precursor tRNAs (pre-tRNAs). The …
