Failure to detect "cap" structures in mitochondrial DNA-coded poly(A)-containing RNA from HeLa cells [PDF]
, 1978 The structure of the 5'-termini has been investigated in mitochondrial DNA- coded poly(A)-containing RNA from HeLa cells. For this purpose, mitochondrial RNA isolated from cells labeled for 3 hours with [32P]orthophosphate in the presence of 20 µg/ml ...

The structure of Rph, an exoribonuclease from Bacillus anthracis, at 1.7 angstrom resolution [PDF]
, 2008 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 ...

A general approach to high-yield biosynthesis of chimeric RNAs bearing various types of functional small RNAs for broad applications. [PDF]
, 2015 RNA research and therapy relies primarily on synthetic RNAs. We employed recombinant RNA technology toward large-scale production of pre-miRNA agents in bacteria, but found the majority of target RNAs were not or negligibly expressed. We thus developed a

Hfq binding changes the structure of Escherichia coli small noncoding RNAs OxyS and RprA, which are involved in the riboregulation of rpoS [PDF]
, 2013 OxyS and RprA are two small noncoding RNAs (sRNAs) that modulate the expression of rpoS, encoding an alternative sigma factor that activates transcription of multiple Escherichia coli stress-response genes. While RprA activates rpoS for translation, OxyS
