• Biophysical properties of residues: Amino acids differ in size and charge. Some are acidic, some are basic, some have aromatic side chains. Generally, replacement of an amino acid with another amino acid with similar properties is less likely to break the protein or cause a dramatic change in function than replacement with an amino acid with different properties. A substitution matrix should ...

[1] Five hours of detailed observations of the asymmetric bow-echo mesoscale convective system on 11–12 June 2000 during the STEPS project are presented. Data sources included polarimetric and Doppler radars, a VHF lightning mapper, and the National Lightning Detection Network. Nearly every (99%) VHF lightning source occurred within 10 km of the convective line. Charge identification within the...

Abstract The wide application of gold nanoparticles has attracted much attention to the development research in nanoparticles. In this study, were prepared by chemical reduction method using potassium tetrachloroaurate as source and sodium borohydride reducer agent. formation was confirmed surface plasmon spectra ultraviolet-visible spectroscopy at wavelength 507 nm. capping process studied two...

In this paper, we used the time-of-flight (TOF) of a charge packet, that injected by a voltage pulse to calculate the drift velocity and mobility of holes in organic semiconducting polymers. The technique consists in applying a voltage to the anode and calculating the time delay in the appearance of the injected carriers at the other contact. The method is a simple way to determine the charge t...

Electronic absorption spectra of proteins are primarily characterized over the ultraviolet region (185–320 nm) of the electromagnetic spectrum. While recent studies on peptide aggregates have revealed absorption beyond 350 nm, monomeric proteins lacking aromatic amino acids, disulphide bonds, and active site prosthetic groups are expected to remain optically silent beyond 250 nm. Here, in a joi...

The contribution of free iron oxides to positive and negative charge distribution has been studied on soils and synthetic kaolinite-iron oxide complexes over a wide range ofpH values. The charge on the iron oxides is pH-dependent, being positive at low and negative at high pH values, respectively, and accounts for a considerable proportion of the pHdependent negative charge in soils. Iron oxide...

The complete nucleotide sequence of the gene encoding the matrix protein (M) of the porcine paramyxovirus LPMV has been determined. The gene is 1376 nucleotides long including 5' and 3' non-coding sequences with a protein-coding sequence of 1107 nucleotides. The deduced protein, containing 369 amino acids with a calculated Mr of 41,657, is hydrophobic overall with a net positive charge of +17.5...

The aim of the present research is to investigate the profile of amino acid of Chlorella vulgaris supplemented with some plant amino acid and oil extracts. The bioactive oil and amino acid from four Iranian medicinal plants, namely Oliveria decumbens, Thymus kotschyanus, Trachyspermum ammi, and Zataria multiflora were obtained. The LC-MS / MS analysis demonstrated that the major amino acids com...
