Composition and conservation of the mRNA-degrading machinery in bacteria [PDF]

open access: yes, 2011
RNA synthesis and decay counteract each other and therefore inversely regulate gene expression in pro- and eukaryotic cells by controlling the steady-state level of individual transcripts.

The number of domains in the ribosomal protein S1 as a hallmark of the phylogenetic grouping of bacteria.

open access: yesPLoS ONE, 2019
The family of ribosomal proteins S1 contains about 20% of all bacterial proteins including the S1 domain. An important feature of this family is multiple copies of structural domains in bacteria, the number of which changes in a strictly limited range ...

The RNA processing enzyme polynucleotide phosphorylase negatively controls biofilm formation by repressing poly-N-acetylglucosamine (PNAG) production in Escherichia coli C

open access: yesBMC Microbiology, 2012
Background Transition from planktonic cells to biofilm is mediated by production of adhesion factors, such as extracellular polysaccharides (EPS), and modulated by complex regulatory networks that, in addition to controlling production of adhesion ...

Proteomic alterations of Escherichia coli by paraquat [PDF]

open access: yes, 2010
Paraquat (PQ; a widely used herbicide) exerts its harmful effect to human, mammals and microorganisms upon intracellular conversion to superoxide radical.

The effect of trypsin digestion on the activities of polynucleotide phosphorylase [PDF]

open access: yesBiochemical Journal, 1967
1. Treatment of Micrococcus lysodeikticus polynucleotide phosphorylase (nucleoside diphosphate–polynucleotide nucleotidyltransferase) with trypsin causes a preferential loss of its cytidine diphosphate and uridine diphosphate polymerization activities. 2.

The role of ribonucleases in regulating global mRNA levels in the model organism Thermus thermophilus HB8 [PDF]

open access: yes, 2014
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 ...

Distinct co-evolution patterns of genes associated to DNA polymerase III DnaE and PolC

open access: yesBMC Genomics, 2012
Background Bacterial genomes displaying a strong bias between the leading and the lagging strand of DNA replication encode two DNA polymerases III, DnaE and PolC, rather than a single one.

Severo Ochoa and the Biomedical Sciences in Spain under Franco, 1959-1975 [PDF]

open access: yes, 2000
The influence of Severo Ochoa in the establishment of biochemistry and molecular biology in Spain is the central topic of this essay. From the time he was awarded the Nobel Prize in Physiology or Medicine in 1959, Ochoa's links with Spanish scientists ...

miRNAs as Influencers of Cell-Cell Communication in Tumor Microenvironment [PDF]

open access: yes, 2020
microRNAs (miRNAs) are small noncoding RNAs that regulate gene expression at the posttranscriptional level, inducing the degradation of the target mRNA or translational repression.
