Structure-Activity Correlations of Amphipathic Cationic AMPs: MD Simulations and Antibacterial Measurement

Antibacterial Activity of Cationic Proteins

A B S T R A, C T Human granulocytes contain several cationic proteins with a molecular weight of approximately 25,000, almost identical amino acid composition, and complete immunologic identity. These proteins possess a chymotrypsin-like protease activity at a neutral pH. The antibacterial activity of the cationic proteins has been studied. Bactericidal activities are found against both Gram-po...

Characterization of Antibacterial Activity and Synergistic Effect of Cationic Antibacterial Peptide-resin Conjugates

We synthesized peptide-resin conjugates (1 and 2) by immobilizing β-sheet antibacterial peptide and α helical antibacterial peptide on PEG-PS resin, respectively. Conjugate 1 showed considerable antibacterial activity in various conditions, whereas conjugate 2 did not exhibit antibacterial activity. The growths of various bacteria were inhibited by conjugate 1 even at lower concentrations than ...

Effects of Solvent on the Structure and Properties of Titanium Dioxide Nanoparticles and Their Antibacterial Activity

Titanium dioxide is semiconductor metal oxide having many applications in photocatalytic activities, cosmetics and in the food industry. It exists in three major crystalline forms: anatase, rutile and brookite. The solvents play a major role in the synthesis, stability and morphology of the metal oxide nanoparticles. It affects both the phase and particle size of metal oxide. T...

Encapsulation of Methane Molecules into C60 Fullerene Nanocage: DFT and DTFB-MD Simulations

Extensive urbanization has greatly raised the demand for cleaner coal- and petroleum-derived fuels. Mainly composed of methane, natural gas represents a promising alternative for this purpose, making its storage a significant topic. In the present research, deposition of methane molecules in C60 fullerene was investigated through a combined approach wherein density functional based tight bindin...
