A new method was developed for the specific and covalent labeling of fusion proteins with small organic probes in vitro and in vivo. The method is based on the construction of fusion proteins of the human O6-alkylguanine-DNA alkyltransferase (hAGT) with a ...
MOTIVATION: The ability of cells to complete mitosis with high fidelity relies on elaborate checkpoint mechanisms. We study S- and M-phase checkpoint responses in silico in the budding yeast with a stochastic dynamical model for the cell-cycle. We aim to p ...
Microfluidic devices are increasingly used to perform biological experiments on a single-cell basis. However, long-term stability of cell positions is still an issue. A novel biocompatible method for cell entrapment and release on a microchip is presented. ...
Many biological processes are driven by biological clocks that, depending on the frequency they generate, are classified into ultradian, circadian and infradian oscillators. In virtually all light-sensitive organisms from cyanobacteria to humans, a circadi ...
We present here the structure of Yer0l0c protein of unknown function, solved by Multiple Anomalous Diffraction and revealing a common fold and oligomerization state with proteins of the regulator of ribonuclease activity A (RraA) family. In Escherichia col ...
Long-range chromosome organization is known to influence nuclear function. Budding yeast centromeres cluster near the spindle pole body, whereas telomeres are grouped in five to eight perinuclear foci. Using live microscopy, we examine the relative positio ...
A novel mutant screen in fission yeast has identified the 'ethanol dependent' protein etd1p as a potential link between the septation initiation network (SIN), which initiates cytokinesis, and the actomyosin contractile ring that drives separation of the t ...
In the fission yeast Schizosaccharomyces pombe, the onset of septum formation is signalled via the septation initiation network (SIN) involving several protein kinases and a GTPase. Arabidopsis thaliana and Brassica napus proteins homologous to fission yea ...
An amperometric method was applied for real-time monitoring of intracellular redox enzyme activity. Baker's yeast (Saccharomyces cerevisiae) cells were immobilized on platinum microband electrodes and mediated anodic currents were measured. The currents we ...
Epigenetic mechanisms silence the HM mating-type loci in budding yeast. These loci are tightly linked to telomeres, which are also repressed and held together in clusters at the nuclear periphery, much like mammalian heterochromatin. Yeast telomere anchori ...
