Comparative analysis of ribonuclease P RNA of the planctomycetes [PDF]
International Journal of Systematic and Evolutionary Microbiology, 2004 The planctomycetes, order Planctomycetales, are a distinct phylum of domain Bacteria. Genes encoding the RNA portion of ribonuclease P (RNase P) of some planctomycete members were sequenced and compared with existing database planctomycete sequences.

Specific Heat upon Aqueous Unfolding of the Protein Interior: A Theoretical Approach [PDF]
, 2001 We study theoretically the thermodynamics, over a broad temperature range (5 C to 125 C), related to hydrated water upon protein unfolding. The hydration effect is modeled as interacting dipoles in an external field, mimicking the influence from the unfolded surfaces on the surrounding water compared to bulk water.

Cloning, expression and location of RNase9 in human epididymis
BMC Research Notes, 2008 Background Mammalian spermatozoa become fully motile and fertile during transit through the luminal fluid of the epididymis. At least 200 proteins are present in the epididymal lumen, but the potential roles of these luminal proteins in male fertility ...

Molecular dynamics of C-peptide of ribonuclease A studied by replica-exchange Monte Carlo method and diffusion theory [PDF]
, 2003 Generalized-ensemble algorithm and diffusion theory have been combined in order to compute the dynamical properties monitored by nuclear magnetic resonance experiments from efficient and reliable evaluation of statistical averages. Replica-exchange Monte Carlo simulations have been performed with a C-peptide analogue of ribonuclease A, and Smoluchowski

BMC Research Notes, 2008 Background Hepatitis delta virus (HDV) is a satellite virus of hepatitis B. During viral replication the 1700-nucleotide-long genomic RNA and its complement, the antigenomic RNA, undergo self-cleavage catalyzed by internal ribozyme motifs that are ...

Ribonucleases P/MRP and the Expanding Ribonucleoprotein World [PDF]
IUBMB Life, 2012 AbstractOne of the hallmarks of life is the widespread use of certain essential ribozymes. The ubiquitous ribonuclease P (RNase P) and eukaryotic RNase MRP are essential complexes where a structured, noncoding RNA acts in catalysis. Recent discoveries have elucidated the three‐dimensional structure of the ancestral ribonucleoprotein complex, suggested ...

Novel Aspects of Polynucleotide Phosphorylase Function in Streptomyces
Antibiotics, 2018 Polynucleotide phosphorylase (PNPase) is a 3′–5′-exoribnuclease that is found in most bacteria and in some eukaryotic organelles. The enzyme plays a key role in RNA decay in these systems.

A possible mechanism for cold denaturation of proteins at high pressure [PDF]
, 2002 We study cold denaturation of proteins at high pressures. Using multicanonical Monte Carlo simulations of a model protein in a water bath, we investigate the effect of water density fluctuations on protein stability. We find that above the pressure where water freezes to the dense ice phase ($\approx2$ kbar), the mechanism for cold denaturation with ...

Microbial Cell Factories, 2011 Background The eukaryotic RNase ribonuclease/angiogenin inhibitors (RI) are a protein group distinguished by a unique structure - they are composed of hydrophobic leucine-rich repeat motifs (LRR) and contain a high amount of reduced cysteine residues ...
