Approximation Algorithms for the Interval Constrained Coloring Problem

We consider the interval constrained coloring problem, which appears in the interpretation of experimental data in biochemistry. Monitoring hydrogen-deuterium exchange rates via mass spectroscopy experiments is a method used to obtain information about pro ...

Sparse Approximations Of Protein Structure From Noisy Random Projections

Victor Panaretos, Kjell Konis

Single-particle electron microscopy is a modern technique that biophysicists employ to learn the structure of proteins. It yields data that consist of noisy random projections of the protein structure in random directions, with the added complication that ...

Long term stabilization of reaction center protein photochemistry by carbon nanotubes

László Forró, Arnaud Magrez, Endre Horvath, Klara Hernadi

The long term stability and the redox interaction between single walled carbon nanotubes (SWNTs) and photosynthetic reaction center proteins (RCs) purified from purple bacterium Rhodobacter sphaeroides R-26 in the SWNT/RC complex has been investigated. The ...

Periplasmic Binding Proteins as Optical Modulators of Single-Walled Carbon Nanotube Fluorescence: Amplifying a Nanoscale Actuator

Ardemis Anoush Boghossian

The authors use glucose-binding protein (GBP) to mech. actuate a fluorescent single-walled carbon nanotube (SWNT), resulting in reversible exciton quenching in response to glucose. The GBP is covalently conjugated with carboxylated poly(vinyl alc.)-wrapped ...

Vibrational entropy and the structural organization of proteins

Paolo De Los Rios, Francesco Piazza

In this paper we analyze the vibrational spectra of a large ensemble of non-homologous protein structures by means of a novel tool, that we coin Hierarchical Network Model (HNM). Our coarse-grained scheme accounts for the intrinsic heterogeneity of force c ...

Polymer Brushes as Substrates for Microarray Applications

Raphaël Barbey

The development of innovative bioanalytical technologies that enable the discovery of new therapeutics or the creation of systems for rapid, accurate and parallel analyses has gained an extraordinary interest in the biomedical sector in the last 10-15 year ...

Synthetic studies toward the CD spiroketal of spongistatins

Pierre Vogel, Sandrine Gerber, Sylvain Favre

Starting from the readily available meso-methylenedi(8-oxa-3-oxobicyclo[3.2.1]hept-6-en-1-yl) (1), meso-1,1'-methylidene [(4R,4'S,6R,6'S)-4,6-dioxycyclohept-1-en-1-yl]tetrasilylethers (7, 8) were obtained and transformed into all-syn 1,3,5,11,13,15-hexahyd ...

Synthesis of sequence-defined oligomers and polymers

Nadja Franz

The preparation of synthetic polymers with exact control over chain length and monomer sequence is one of the long-standing challenges in polymer science. Nature perfectly masters the synthesis of high molecular weight, perfectly monodisperse polypeptides ...

Discrete breathers in protein structures

Francesco Piazza

Recently, using a numerical surface cooling approach, we have shown that highly energetic discrete breathers (DBs) can form in the stiffest parts of nonlinear network models of large protein structures. In the present study, using an analytical approach, w ...

Supramolecular structures of polypeptides

Daniela Silvano

The formation of supramolecular structures is a central issue in bio- and nanotechnology and therein plays an important role for many novel developments such as biocompatible materials for integrating living cells or coating for implantable sensing devices ...
