abstract global financial crisis has created too many problems in relations among governments. among these problems, the issue of global monetary management, more than every time in the past four decades, has been moved in the center of international economic attentions. a problem which is specially known with the monetary hostility between united states and public republic of china. where ar...
Production of antimicrobial peptides and proteins is an important means of host defense in eukaryotes. The larger antimicrobial proteins, containing more than 100 amino acids, are often lytic enzymes, nutrient-binding proteins or contain sites that target specific microbial macromolecules. The smaller antimicrobial peptides act largely by disrupting the structure or function of microbial cell m...
Background: Xanthomonas citri subsp. citri (Xcc), the causative agent of bacterial citrus canker, has affected citriculture worldwide. Varieties of means have been used to minimize its devastating effects, but no attention has been given to bacteriocins. Objectives: Here and for the first time, we report the isolation and characterization of two novel bacteriocins. Materials and Methods: Secret...
Background: Antimicrobial peptides have been considered as the key to change in the current antibiotics. AcAMP, Antimicrobial peptide is one of them, which has been purified from the Aspergillus clavatus ES1 fungus, and its biochemical properties and characterization indicate that this peptide has unique properties. The aim of this study was to express the gene of AcAMP peptide in Escherichia c...
The rapid increase in drug-resistant infections has presented a serious challenge to antimicrobial therapies. The failure of the most potent antibiotics to kill "superbugs" emphasizes the urgent need to develop other control agents. Here we review the history and new development of antimicrobial peptides (AMPs), a growing class of natural and synthetic peptides with a wide spectrum of targets i...
Antimicrobial peptides (AMPs) are small molecular weight proteins with broad spectrum antimicrobial activity against bacteria, viruses, and fungi. These evolutionarily conserved peptides are usually positively charged and have both a hydrophobic and hydrophilic side that enables the molecule to be soluble in aqueous environments yet also enter lipid-rich membranes. Once in a target microbial me...
Subcellular localization is important for proteins to function. For the prediction of subcellular localizations, we have developed a method, SortPred, using the amino acid composition and order. The composition represents the global features, e.g., the amino acid composition in the full or partial sequences, while the order represents the local features, e.g., the amino acid sequence order. The...
The effectiveness of antimicrobial compounds can be easily screened, however their mechanism of action is much more difficult to determine. Many compounds act by compromising the mechanical integrity of the bacterial cell envelope, and our study introduces an AFM-based creep deformation technique to evaluate changes in the time-dependent mechanical properties of Pseudomonas aeruginosa PAO1 bact...
