NICEdrug.ch, a workflow for rational drug design and systems-level analysis of drug metabolism

Vassily Hatzimanikatis, Jasmin Maria Hafner, Homa Mohammadi Peyhani, Noushin Hadadi, Anush Chiappino-Pepe

The discovery of a drug requires over a decade of intensive research and financial investments – and still has a high risk of failure. To reduce this burden, we developed the NICEdrug.ch resource, which incorporates 250,000 bioactive molecules, and studied ...

The SCF-FBXW5 E3-ubiquitin ligase is regulated by PLK4 and targets HsSAS-6 to control centrosome duplication

Pierre Gönczy, Debora Keller

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 ...

Electrochemical Promotion and Metal-Support Interactions

Christos Comninellis

Ethylene oxidn. on IrO2, which is a metal-type conducting metal oxide, and on Pt and Rh was used as a model reaction to compare the rate enhancement and kinetic modification induced by (i) electrochem. promotion (non-Faradaic electrochem. modification of c ...

A comparative study of galactose oxidase and active site analogs based on QM/MM Car-Parrinello simulations

Ursula Röthlisberger, Michele Parrinello, Paolo Carloni

A parallel study of the radical copper enzyme galactose oxidase (GOase) and a low mol. wt. analog of the active site was performed with dynamic d. functional and mixed quantum-classical calcns. This combined approach enables a direct comparison of the prop ...

Rational design of biomimetics with QM/MM Car-Parrinello simulations

Ursula Röthlisberger

A parallel study of the radical-copper enzyme Galactose Oxidase (GOase) and a low mol. wt. analog of the active site (Wang et. al. , Science 279, 537 (1998)) was performed with dynamical d. functional and mixed quantum-classical (QM/MM) calcns. This combin ...

Impaired natural killing of MHC class I-deficient targets by NK cells expressing a catalytically inactive form of SHP-1

Béatrice Kunz, Friedrich Beermann

NK cell function is negatively regulated by MHC class I-specific inhibitory receptors. Transduction of the inhibitory signal involves protein tyrosine phosphatases such as SHP-1 (SH2-containing protein tyrosine phosphatase-1). To investigate the role of SH ...

Activation of a Plasmodium falciparum cdc2-related kinase by heterologous p25 and cyclin H. Functional characterization of a P. falciparum cyclin homologue

Several Plasmodium falciparum genes encoding cdc2-related protein kinases have been identified, but the modalities of their regulation remains largely unexplored. In the present study, we investigated the regulation in vitro of PfPK5, a putative homologue ...

Ab initio molecular dynamics studies of a synthetic biomimetic model of galactose oxidase

Ursula Röthlisberger, Paolo Carloni

Very recently, highly efficient biomimetic models of the mononuclear copper enzyme galactose oxidase were synthesized which are able to reproduce the structural, spectroscopic, and functional properties of the native system exceptionally well. We have char ...
