AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Organohalide respiration (previously named as dehalorespiration) is a process during which microbes derive energy by the reductive dehalogenation of chlorinated organic pollutants and use them as terminal electron acceptors, hence helping in environmental ...
Cell-based assays for the inhibition of viral infections most commonly couple a positive signal (e.g., an increase in fluorescence) to the infection itself and not to its inhibition. When performing drug screens, compounds decreasing the signal are therefo ...
Engrailed 2 is a transcription factor belonging to the class of homeoproteins. These proteins possess a 60-residue DNA binding globular domain and play an important role in the early stages of development. We expressed and purified a 13.4 kDa fragment of E ...
We introduce here a new class of BODIPY-based Ca2+ indicators which can be derivatized with biological ligands that permit the localization of the indicators in living cells. The underivatized BODIPY-based Ca2+ indicator (BOCA-1) shows a 250-fold increase ...
Malaria is the most devastating parasitic infection killing each year between 1 and 3 million of people. Furthermore this decease has a huge socio-economic impact in affected countries. The emergence of resistance against currently used drug makes the deve ...
Deregulated centrosome duplication can result in genetic instability and contribute to tumorigenesis(1,2). Here, we show that centrosome duplication is regulated by the activity of an E3-ubiquitin ligase that employs the F-box protein FBXW5 (ref. 3) as its ...
The human pathogen Mycobacterium tuberculosis requires the ESX-1 secretion system for full virulence. EspR plays a key role in ESX-1 regulation via direct binding and transcriptional activation of the espACD operon. Here, we describe the crystal structures ...
Imagine a small integrated biomedical analysis laboratory, connected to your home computer, which would be capable of diagnosing illnesses, a lack of vitamins, or the over-presence of substances from samples of blood, urine or saliva. This hypothetic syste ...
Remarkable progress has been made during the past ten years in elucidating the structure of the bacteriophage T4 tail by a combination of three-dimensional image reconstruction from electron micrographs and X-ray crystallography of the components. Partial ...
Polypropionates are common products of metabolism in bacteria, insects, fungi and marine organisms. They constitute an important class of products with a wide range of interesting biological activities. Our group has shown previously that 1-alkoxy-3-acylox ...
