The first method for the [3 + 2] annulation of donor acceptor aminocyclopropanes with aldehydes is reported. The reaction is catalyzed by iron trichlorlde on alumina in yields up to 99% and with excellent cis selectivities (up to >20:1) and represents a st ...
Background: The HIV-1 genome is subject to pressures that target the virus resulting in escape and adaptation. On the other hand, there is a requirement for sequence conservation because of functional and structural constraints. Mapping the sites of select ...
Telomeres, the physical ends of eukaryotic chromosomes, consist of tandem arrays of short DNA repeats and a large set of specialized proteins. A recent analysis has identified telomeric repeat-containing RNA ( TERRA), a large non-coding RNA in animals and ...
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 ...
During a previous, exploratory project in our group, it was observed that duplexes formed by oligonucleotides modified with polar 2'-O-substituents were more tolerant towards the addition of 1,2-dimethoxyethane (DME) than RNA and DNA duplexes [1]. Inspired ...
In vitro transcription and translation reactions have become popular for a bottom-up approach to synthetic biology. Concentrations of the mRNA intermediate are rarely determined, although knowledge of synthesis and degradation rates could facilitate ration ...
The human EST1A/SMG6 polypeptide physically interacts with the chromosome end replication enzyme telomerase. In an attempt to better understand hEST1A function, we have started to dissect the molecular interactions between hEST1A and telomerase. Here, we d ...
We describe a point mutation creating an additional ATG codon in the 5' untranslated region (UTR) of the HAMP gene, in a patient with juvenile hemochromatosis. By transient in vitro transfection studies, we provide evidence that the additional ATG is funct ...
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 ...
DNA uptake by polyethylenimine (PEI)-mediated transfection was investigated in Chinese hamster ovary (CHO DG44) cells. Rapid DNA uptake was observed with the maximum occurring during the first 45-60 min after addition of PEI-DNA complexes to cells. With lo ...
