B12-BIOSYNTHESIS IN THE TETRACHLOROETHENE-RESPIRING OBLIGATE ANAEROBE DESULFITOBACTERIUM

Christof Holliger, Julien Maillard, Aurélie Duret

Tetrachloroethene (PCE) reductive dehalogenases are the key catalysts in the respiratory chain of dehalorespiring microorganisms, where they act as the terminal electron-accepting enzymes in the process. On protein level, reductive dehalogenases have been ...

The crystal structure of the Escherichia coli RNase E apoprotein and a mechanism for RNA degradation

RNase E is an essential bacterial endoribonuclease involved in the turnover of messenger RNA and the maturation of structured RNA precursors in Escherichia coli. Here, we present the crystal structure of the E. coli RNase E catalytic domain in the apo-stat ...

New efficient synthetic routes toward functionalised polyketides

Gérald Coste

RNA plays key roles in essential biological processes, such as protein synthesis, transcriptional regulation, splicing and retroviral replication. The structural diversity of RNA molecules and the lack of known RNA repair mechanisms make these biopolymers ...

New methods for the investigation of RNA refolding by NMR spectroscopy

Philipp Wenter

A detailed characterization of the time scales and mechanisms by which RNA molecules change their folding structure upon binding of metabolites or during catalysis is important for the understanding of the different biological functions of RNA. The folding ...

Optimized methods for the enzymatic ligation of oligoribonucleotides and analogues

Frédéric David Meylan

The preparation of oligoribonucleotides is of great interest for structural and functional investigations in biomolecular chemistry and biology. Relevant RNAs are relatively long and contain often modifications. Two methods for their preparation are curren ...

Structure of Escherichia coli RNase E catalytic domain and implications for RNA turnover

The coordinated regulation of gene expression is required for homeostasis, growth and development in all organisms. Such coordination may be partly achieved at the level of messenger RNA stability, in which the targeted destruction of subsets of transcript ...

Chloroethenes, and most particularly tetra- (PCE) and trichloroethene (TCE) are major groundwater pollutants due to their extensive industrial use as solvents since the 1920s. The strong electronegativity of the chlorines renders them very stable under aer ...

Pentopyranosyl oligonucleotide systems. 9. The b-D-ribopyranosyl-(4'->2')-oligonucleotide system (\"pyranosyl-RNA\"): Synthesis and resume of base-pairing properties

Pyranosyl-RNA ("p-RNA") is an oligonucleotide system isomeric to natural RNA and composed of the very same building blocks as RNA. Its generational, chem., and informational properties are deemed to be those of an alternative nucleic acid system that cou ...

We investigated the expression of several mRNAs in exoerythrocytic and erythrocytic stages of Plasmodium yoelii in infected mice, focusing our attention on genes thought to be involved in signal transduction (like pypka and pymap-1, encoding homologues of ...

Specialists for RNA synthesis

In contrast to DNA-related research, RNA-related research is limited by the availability of synthetic sequences. Recent improvements in chem. synthesis allow Xeragon AG to offer custom RNA sequences - up to 100mers - in high quantity and quality at an affo ...
