The structure of Rph, an exoribonuclease from Bacillus anthracis, at 1.7 angstrom resolution [PDF]
Maturation of tRNA precursors into functional tRNA molecules requires trimming of the primary transcript at both the 5' and 3' ends. Cleavage of nucleotides from the 3' stem of tRNA precursors, releasing nucleotide diphosphates, is accomplished in ...

The role of ribonucleases in regulating global mRNA levels in the model organism Thermus thermophilus HB8 [PDF]
BACKGROUND: RNA metabolism, including RNA synthesis and RNA degradation, is one of the most conserved biological systems and has been intensively studied; however, the degradation network of ribonucleases (RNases) and RNA substrates is not fully ...

Mitochondrial Genome Engineering: The Revolution May Not Be CRISPR-Ized. [PDF]
In recent years mitochondrial DNA (mtDNA) has transitioned to greater prominence across diverse areas of biology and medicine. The recognition of mitochondria as a major biochemical hub, contributions of mitochondrial dysfunction to various diseases, and

Critical roles for ‘housekeeping’ nucleases in type III CRISPR-Cas immunity
CRISPR-Cas systems are a family of adaptive immune systems that use small CRISPR RNAs (crRNAs) and CRISPR-associated (Cas) nucleases to protect prokaryotes from invading plasmids and viruses (i.e., phages).

Polynucleotide Phosphorylase from a Cyanobacterium (Synechococcus sp.): Subunit Composition and Properties [PDF]
Polynucleotide phosphorylase from cells of the cyanobacterium Synechococcus sp. has been purified 1400-fold by an improved procedure. The enzyme purified to homogeneity and lacking nuclease, phosphatase and protease contaminations reveals a single band ...

Crystal structure of Caulobacter crescentus polynucleotide phosphorylase reveals a mechanism of RNA substrate channelling and RNA degradosome assembly [PDF]
Polynucleotide phosphorylase (PNPase) is an exoribonuclease that cleaves single-stranded RNA substrates with 3′–5′ directionality and processive behaviour.
