The epidermal growth factors (EGFs) are powerful mitogens for a wide variety of cells in culture; human EGF (hEGF), known as urogastrone, also inhibits gastric acid secretion in vivo. The transforming growth factors (TGF-alpha) are related to the EGF family both in sequence and activity and EGF-like sequences are often observed in a wide range of(More)
The conformation of the 26-residue polypeptide melittin has been studied using 1H-NMR spectroscopy in methanolic solution. The 1H-NMR spectrum of melittin has been assigned using two-dimensional NMR techniques and the secondary structure has been calculated from nuclear Overhauser enhancement data using distance geometry and restrained molecular dynamics(More)
Using a combination of 1H NMR nuclear Overhauser effect measurements, molecular orbital calculations, and molecular dynamics simulations, we have determined the tertiary structure and dynamic properties of the oligomannose oligosaccharide Man alpha 6(Man alpha 3)Man alpha 6(Man alpha 3)Man beta 4GlcNAc beta 4GLcNAc. While the calculated potential surfaces(More)
The 26-residue toxin from Staphylococcus aureus, delta-hemolysin, is thought to act by traversing the plasma membrane. The structure of this peptide, in methanol solution, has been investigated by using high-resolution NMR in combination with molecular dynamics calculations. The 1H NMR spectrum has been completely assigned, and it is shown that residues(More)
Biological plausibility and other prior information could help select genome-wide association (GWA) findings for further follow-up, but there is no consensus on which types of knowledge should be considered or how to weight them. We used experts' opinions and empirical evidence to estimate the relative importance of 15 types of information at the(More)
Molecular dynamics simulations are described for the peptide melittin. The atomic trajectories are calculated both with normal potential energy functions and with additional distance restraints deduced from nuclear Overhauser effects observed in NMR experiments. The results are compared with NMR data on coupling constants and amide exchange rates and with(More)

Prioritization is the process whereby a set of possible candidate genes or SNPs is ranked so that the most promising can be taken forward into further studies. In a genome-wide association study, prioritization is usually based on the P-values alone, but researchers sometimes take account of external annotation information about the SNPs such as whether the(More)
