Dependence of ethanol effects on protein charges [PDF]
, 2014 Ethanol is used as a conventional disinfectant solution. It is highly effective against enveloped viruses due to its effects on virus membranes. It also confers inactivation of non-enveloped viruses, which can be ascribed to conformational changes or ...

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 ...

Sinorhizobium meliloti RNase III: Catalytic Features and Impact on Symbiosis
Frontiers in Genetics, 2018 Members of the ribonuclease (RNase) III family of enzymes are metal-dependent double-strand specific endoribonucleases. They are ubiquitously found and eukaryotic RNase III-like enzymes include Dicer and Drosha, involved in RNA processing and RNA ...

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 ...

The occupancy of two distinct conformations by active-site histidine-119 in crystals of ribonuclease is modulated by pH [PDF]
, 1994 Structures of a semisynthetic RNase have been obtained to a resolution of 2.0 Å at pH values of 5.2, 6.5, 7.5, and 8.8, respectively. The principle structural transformation occurring over this pH range is the conversion of the side chain of active site ...

Recognition of Ribosomal RNA Sites in DNA, I. Analysis of the E. coli System [PDF]
, 1965 The evidence recently presented of specific hybridization between bacterial ribosomal RNA and homologous DNA1-3 has indicated the possibility of a biochemical approach to the problem of the identification of ribosomal RNA sites in DNA.

Chemical evolution of an autonomous DNAzyme with allele-specific gene silencing activity
Nature Communications, 2023 Low activity has been the primary obstacle impeding the use of DNA enzymes (DNAzymes) as gene silencing agents in clinical applications. Here we describe the chemical evolution of a DNAzyme with strong catalytic activity under near physiological ...

Detection of DNA-RNA hybrids in vivo [PDF]
, 2017 DNA-RNA hybrids form naturally during essential cellular functions such as transcription and replication. However, they may be an important source of genome instability, a hallmark of cancer and genetic diseases.
