MOTIVATION The limited availability of protein structures often restricts the functional annotation of proteins and the identification of their protein-protein interaction sites. Computational methods to identify interaction sites from protein sequences alone are, therefore, required for unraveling the functions of many proteins. This article describes a(More)
MOTIVATION All eukaryotic proteomes are characterized by a significant percentage of proteins of unknown function. Comp-utational function prediction methods are therefore essential as initial steps in the function annotation process. This article describes an annotation method (PiRaNhA) for the prediction of RNA-binding residues (RBRs) from protein(More)
The PiRaNhA web server is a publicly available online resource that automatically predicts the location of RNA-binding residues (RBRs) in protein sequences. The goal of functional annotation of sequences in the field of RNA binding is to provide predictions of high accuracy that require only small numbers of targeted mutations for verification. The PiRaNhA(More)
The optical transition energies, E 11 and E 22 , of single-walled carbon nanotubes (SWNTs) suspended in air have been investigated for 20 species by photoluminescence and excitation spectro-scopies. We h a ve studied the environmental eects in photoluminescence by comparing our results with those for the SWNTs wrapped by sodium-dodecyl-sulfate (SDS), as(More)
Single-walled carbon nanotubes with narrow diameter-distributions were synthesized by the catalytic CVD technique using fullerene, C 60 or C 70 , as the carbon source. Fe/Co bimetal particles supported with zeolite powder were exposed to fullerene vapor in a heated quartz tube furnace. With a precise control of fullerene vapor pressure, macroscopic amounts(More)
Nanomaterials continue to attract widespread attention in many scientific and technological fields. The sizes and shapes of nanomaterials determine their physical and chemical properties. We have developed an analytical system for single nanomaterials that combines capillary electrophoresis (CE) with a highly sensitive detection method. In this manuscript,(More)
UNLABELLED SHARP2 is a flexible web-based bioinformatics tool for predicting potential protein-protein interaction sites on protein structures. It implements a predictive algorithm that calculates multiple parameters for overlapping patches of residues on the surface of a protein. Six parameters are calculated: solvation potential, hydrophobicity,(More)
We have developed a method to predict ligand-binding sites in a new protein structure by searching for similar binding sites in the Protein Data Bank (PDB). The similarities are measured according to the shapes of the molecular surfaces and their electrostatic potentials. A new web server, eF-seek, provides an interface to our search method. It simply(More)
Anisotropic optical absorption properties of single-walled carbon nanotubes (SWNTs) are determined from a vertically aligned SWNT film for 0.5-6 eV. Absorption peaks at 4.5 and 5.25 eV are found to exhibit remarkable polarization dependence and have relevance to optical properties of graphite. A method for determining a nematic order parameter for an(More)
