Deciphering the Underlying Mechanism for Au/ZnO Nanocomposites-Induced Modulation of Structural Features and Thermodynamic Stability of Horse Myoglobin. Au/ZnO nanocomposites (NCs) were synthesized and characterized by using various analytical techniques. Analysis of Au/ZnO NCs effect on H NMR, CD, fluorescence, and absorbance spectra of horse myoglobin (-Mb) at 0.0 and 5.0 M urea (pH 7.4) revealed that the Au/ZnO NCs weaken the heme-globin interactions and also disrupt the secondary/tertiary structure of -Mb. Furthermore, the Au/ZnO NCs effect of weakening the heme-globin interactions and disrupting the protein structures was detected more in the denaturant media than in the aqueous solution. Analysis of the Au/ZnO NCs effect on thermodynamic...
Lipoprotein complex of equine lysozyme with oleic acid (ELOA) interactions with the plasma membrane of live cells. Recent evidence supports the idea that early aggregates, protein, and lipoprotein oligomers but not large aggregates like fibrils that are formed at late stages of the aggregation process are responsible for cytotoxicity. Oligomers can interact with the cellular plasma membrane affecting its structure and/or dynamics or may be taken up by the cells. In either case, disparate cascades of molecular interactions are activated in the attempt to counteract the disturbance induced by the oligomers. If unsuccessful, cell death follows. Here, we study the molecular and cellular mechanisms underlying P...
Reorganization of immobilized horse and yeast cytochrome c induced by pH changes or nitric oxide binding. The redox properties of horse and yeast cytochrome c electrostatically immobilized on carboxylic acid-terminated self-assembled monolayers (SAMs) have been determined over a broad pH range (pH 3.5-8) in the absence and presence of nitric oxide. Below pH 6, both proteins exhibit comparable midpoint potentials, coverages, and electron-transfer rate constants, which suggests that they are adsorbed on the SAM in a similar fashion. Above pH 6, a sharp decrease in electron-transfer rate constants is observed for immobilized yeast cytochrome c, which is indicative of a change in the electron tunnelin...
Miscibility of binary monolayers at the air-water interface and interaction of protein with immobilized monolayers by surface plasmon resonance technique. The miscibility and stability of the binary monolayers of zwitterionic dipalmitoylphosphatidylcholine (DPPC) and cationic dioctadecyldimethylammonium bromide (DOMA) at the air-water interface and the interaction of ferritin with the immobilized monolayers have been studied in detail using surface pressure-area isotherms and surface plasmon resonance technique, respectively. The surface pressure-area isotherms indicated that the binary monolayers of DPPC and DOMA at the air-water interface were miscible and more stable than the monolayers of the two individual components. The surface plasmon re...
